The different excitation wavelengths are supplied by up to three internal laser and eventually by one external laser. The confocal microscope is coupled to a 460 mm focal length spectrograph equipped with a four interchangeable gratings turret. The LabRAM Aramis is an integrated confocal microRaman system. Raman can best be thought of as producing a precise spectral fingerprint, unique to a molecule or indeed and individual molecular structure or chemical bonding. This energy loss is characteristic for a particular bond in the molecule. The amount of energy lost is seen as a change in energy (wavelength) of the irradiating photon. With Raman spectroscopy, a laser photon is scattered by a sample molecule and loses (or gains) energy during the process. The Raman scattering technique is a vibrational molecular spectroscopy which derives from an inelastic light scattering process.

The APEX2 software features a redesigned start-to-finish graphical user interface (GUI) along with the optional Phase ID and Auto Structure software modules. The instrument is presently equipped with Mo-radiation and an Oxford Cryo-system low temperature system can be added to perform data collection down to 100K.īruker SMART APEX Software system provides the tools for complete small molecule structure determination. The instrument is producing data of quality for both routine structure determination and for high accuracy and high resolution data.ĭata collection can take from a couple of hours to a day depends of the crystal quality and crystal symmetry.
Its use has thus become an essential tool for new discovery.
