In both cases, there is at least one normal mode outside the six lowest-frequency modes with pseudo-translational and pseudo-rotational contributions exceeding 10 %. For these normal modes, the projection substantially impacts the frequencies and intensities. Specifically for uracil in methanol, normal mode 8 has 14 % each pseudo-translational and pseudo-rotational where the change in frequency is about 129 cm -1 , about 383 % for the Raman intensity, and about 64 % for the IR intensity. For the aforementioned normal modes with high relative differences, the absolute differences are also substantial and will thus lead to major differences in the spectra.
