Notes:
We demonstrate the rapid recording of liquid phase anti-Stokes vibrational and gas phase rotational spectra with an unintensified solid state detector. The ratio of the Stokes and anti-Stokes intensities of the 522 cm-1 vibration of toluene (Wilson 6a) does not appear to agree with theoretical predictions, in contrast to nearby lines. This possibility of a direct comparison accentuates the advantage of the simultaneous multichannel recording without drift. We also discuss the signal-to-noise performance of unintensified detectors and point out the limits where intensification is preferable.
