| Abstract: | Extensions in frequency coverage coupled with sensitive spectroscopic techniques have enabled high resolution measurements of pure rotational spectra of deuteromethane and its 13-C substituted counterpart up to J′=7. The current work reveals a small inconsistency in previously reported frequency measurements of 12CH3D at J′=5. |
