Rotational spectroscopy as a tool to investigate interactions between vibrational polyads in symmetric top molecules: low-lying states $v_8\le 2$ of methyl cyanide, CH${}_3$CN

Holger S. P. Müller, Linda R. Brown, Brian J. Drouin +6

Spectra of methyl cyanide were recorded to analyze interactions in low-lying vibrational states and to construct line lists for radio astronomical observations as well as for infra…
