Laboratory of Spectroscopy for Interactions, Reactivity and Environment (LASIRE)

Research unit - UMR 8516

Description

The field of expertise of our laboratory encompasses various types of spectroscopy, including vibrational (RAMAN scattering, infrared absorption, neutron scattering), electronic (UV-visible absorption, fluorescence), magnetic (NMR and EPR) as well as analytical techniques (HPLC-GC and ICP MS/AES). We are also specializing in separative techniques as well as molecular modeling techniques and chemometrics. The main field of application of our laboratory is physical chemistry and more specifically molecular spectroscopies applied to the study of complex physico-chemical systems: natural systems, photo-active chemical systems, biomaterials, materials with organic and inorganic radicals, etc. The unit is composed of four teams and also coordinates several technological platforms. Our partnership policy aims at developing research with private companies as well as with public organizations, agencies and communities.

Equipments

We possess a wide range of equipment regrouped within the technological platforms. Some of these platforms have national (RENARD Infrastructure FR3443) or site (Vibrational Spectroscopy Platform and Plasma Torch Spectrometry Platform) accreditation, others are our internal shared facilities. Our equipment includes:
• double beam UV-vis spectroscopy instruments: routine and high-end
• routine spectrofluorometers (Fluoromax3 (Horiba) and Cary Eclipse (Varian))
• modular fluorometer (Fluorolog 3 (Horiba))
• Atomic Force Microscope (NTEGRA, NT-MDT) equipped with an environmental cell
• femtosecond, picosecond and nanosecond laser sources
• devices for the generation and detection of optical pulses
• transient spectroscopy devices
