The Vibrational Spectra of Pyridine and Pyridine‐d5

Pyridine‐d5 has been prepared by exchange between pyridine vapor and heavy water in the presence of a palladium catalyst. Infrared and Raman spectra are reported for pyridine and pyridine‐d5 over the spectral range 300–4000 cm−1. Interpretation of the spectra with the help of the product rule and by analogy with the fundamental frequencies of benzene and benzene‐d6 leads to complete sets of frequencies for the 27 vibrational degrees of freedom of pyridine and of pyridine‐d5. The frequency assignment for pyridine does not differ greatly from previous ones, but is believed to be more reliable because of the additional spectroscopic data.
