A Simple Method for Accurate Wavenumber Determination in High-resolution CARS Spectroscopy
Abstract:As is well known, in coherent anti-Stokes Raman spectroscopy (CARS), the frequency ωR of molecular vibrations or rotations is determined by the difference in frequency of the applied laser beams with fixed (ω1) and with tunable frequency (ω2), i.e., ωR = ω1 − ω2. For low resolution CARS experiments (∼0.1 to 1 cm−1), it is usually sufficient to measure the frequencies of the two laser beams by means of a spectrometer which has been calibrated before using emission lines of discharge lamps. The accuracy in frequency determination applying this method is limited to be approximately ±0.1 to ±0.5 cm−1.
