New Investigation of Millimeter‐Wave Rotational Spectrum of CCl 3 CN in Ground, v 7 = 1 and v 8 = 1 States
The millimeter‐wave rotational spectra of the ground and excited vibrational states v 7 =1 and v 8 =1 of the symmetric top molecule, CCl 3 CN, have been analyzed again. The B 0 = 1666.80894(13) MHz, D J = 0.135023 (23) kHz, D JK = 0.60596 (45) kHz, H J = ‐0.0192 (10) mHz, H JK = 1.188 (34) mHz and H...
