    The ICMAB Spectroscopy Service was created with the main objective to provide centralised equipments and installations mainly to the research ICMAB groups though the service is also opened to external users.

    The priority of this service is to offer the highest levels of technology and quality to satisfy the requirements of the research lines currently underway in our institute.

    The currently equipments available are: NMR, EPR, RAMAN, UV-Vis-NIR, FT-IR and Luminescence spectrometers. For NMR, EPR and RAMAN equipments highly qualified technical staff is employed. The rest of the equipments are mainly used on a self-service regime.

    Three types of spectroscopy techniques have been carried out:

    a) Molecular spectroscopy: The systems available in our laboratory allow analytical and physic-chemical studies of organic and inorganic molecules (in solid or liquid state) in the ultraviolet, visible and infrared energy range. b) Nuclear Magnetic Resonance: The available systems in this service allow to carry out 1D and 2D 1H NMR, 13C NMR, 11B NMR, 31P NMR, 29Si NMR, etc in solution. c) Electron Paramagnetic Resonance: The EPR allows to detect and study transient and stable paramagnetic species such as free radicals, over a very wide range of temperatures.

  • User's Commission

    The User Commission integrates researchers from several groups, as well as the Service staff and the Service manager. Its main task is to supervise all aspects related to the correct operation of the Service.

    It is formed by the following staff:

    • Dr. José Vidal Gancedo (Service Manager)
    • Prof. Clara Viñas
    • Prof. Concepció Rovira
    • Prof. David Amabilino
    • Dr. Narcís Mestres
    • Dr. Rosario Núñez
    • Dr. Susagna Ricart

  • Equipment

    • FTIR
      Spectrometer Perkin-Elmer Spectrum One. Energy range: 450-4000 cm-1. Powder samples can be measured making KBr pellets, and liquid samples between two NaCl pellets. The Service is provided with a Universal Attenuated Total Reflectance accessory (U-ATR) for powder samples, films, polymers, etc.
      This equipment is of self-service management for internal users, who have been previously trained by the technicians. However, the technicians are needed for the external users.
    • UV-Vis-NIR
      There are two double beam UV-Vis-NIR spectrophotometer, a Varian Cary 5 and a Varian Cary 5000 with operational range of 190-3300 nm and also a Shimadzu UV-Vis 1700 spectrophotometer with operational range of 200-800 nm.
      Liquid samples
      can be measured in absorbance or transmittance mode mainly using 1 cm or 1 mm quartz cuvettes. The three equipments are of self-service management for internal users, who have been previously trained by the technicians. However, the technicians are needed for the external users.

      For solid samples it is available a Diffuse Reflectance Sphere DRA-2500 accessory in the UV-Vis-NIR Varian Cary 5000 spectrophotometer, with operational range of 190-3300 nm. Solid samples can be measured mainly in reflectance or transmittance mode.
      A qualified technician is always needed for running the DRA-2500 accessory.

    • Luminescence spectrometer
      Luminescence spectrometer Perkin Elmer LS45. Spectral range of the excitation monochromator is 200-800 nm and the spectral range of the emission monochromator is 200-900 nm.
      This equipment is of self-service management for internal users, who have been previously trained by the technicians. However, the technicians are needed for the external users.
    • EPR
      Bruker ELEXYS E500 X band EPR spectrometer equipped with a variable temperature unit, a field frequency (F/F) lock accessory and built in NMR Gaussmeter. There are different cavities for the different measurements needed. A qualified technician is always needed for running this equipment.
    • NMR
      Bruker Avance II 300: Equipped with two probes, one of them is a QNP-z (1H/13C/19F/31P),which is used for routine experiments, and the other is a probe of broad band of inverse detection (1H/31P-109Ag) with accessory for low temperature
    • RAMAN
      Renishaw RAMAN microespectrometer formed by a dispersion RAMAN espectrometer that incorporates a several lines of excitation laser and a confocal microscopy to study the composition, the chemical and molecular structure, and the microscopy heterogeneous of different materials with high space resolution.

    GENERAL PROCEDURE
     
    • Internal users (from ICMAB):

      First contact with the Service Technicians Vega Lloveras ( This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 300, 311) or Anna Fernández ( This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 316, 298). They will train the users to manage the equipment by themselves because it works in a self-service regime for internal users.

      All users must register in the note-book of the equipment every time they use it, pointing out the time they have spent doing the measurement, the group's IP and the project's number.

    • External users (other public centres and companies):

      First contact with the Service Technicians Vega Lloveras ( This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 300, 311) or Anna Fernández ( This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 316, 298) in order to arrange the details of the measurements. At the same time, a service form must be filled in. Every equipment has its own service form. There exists the possibility of working with the apparatus in a self-service regime.
      In addition to this, all users must also register in the note-book of the equipment every time they use it.
