The technique of measuring vibrational circular dichroism (VCD) in the mull phase will be $describted.1$ Examples of such spectra for the molecules (+)-3-bromocamphor, L-tyrosylglycine, glycyl-L-tyrosine, and other molecules will be presented. Differences between mull phase and solution spectra for the same molecules will be discussed. The relation of such differences to the particle size in the mull sample and the Christiansen filter $effect2$ will be explored.
