    The FT-IR spectra were recorded using a Nicolet 170SX or a JASCO FT/IR-410 spectrometer. For spectra recorded in the Nicolet spectrometer, the data were stored at intervals of 0.5 cm −1 in the 4,000 – 2,000 cm −1 region and of 0.25 cm −1 in the 2,000 – 400 cm −1 region and the spectral resolution was 0.25 cm −1.

  6. Infrared multiphoton dissociation - Wikipedia

    en.wikipedia.org/wiki/Infrared_multiphoton...

    By applying intense tunable IR lasers, like IR-OPOs or IR free electron lasers, the wavelength dependence of the IRMPD yield can be studied. [5] [6] This infrared photodissociation spectroscopy allows for the measurement of vibrational spectra of (unstable) species that can only be prepared in the gas phase. Such species include molecular ions ...
