The microwave rotational spectrum of the hydrogen-bonded heterodimer CH 3 CN • • • HF has been identified and shown to be characteristic of a symmetric top. A detailed analysis of several rotational transitions for a variety of isotopic species gives the spectroscopic constants summarized in the following table: Rotational constants/MHz, vibration-rotation constants/MHz and vibrational separations/cm -1 of CH 3 CN • • • HF

Simulation Of Spectra

The rotational spectrum of the hydrogen cyanide dimer has been observed in the frequency range 26-40 GHz by using a Stark-modulated microwave spectrometer. Although the spectrum is very weak, even under optimum conditions, it has been possible to assign vibrational satellites in the v β progression based on the ground state and in the v β progression based on v σ ═ 1 with the aid of the computer simulation of spectra and the ground-state spectroscopic constants. The spectroscopic constants now available for the hydrogen cyanide dimerare summarized as follows: (HC 14 N) 2 (DC 14 N) 2 (HC 15 N) 2 v β ═ 1 ← 0/cm -1 35±5 30±5 35±5 v σ ═ 1 ← 0/cm -1 101 ─ ─ B o /MHz 1745.80973(50) 1661.18(26) 1684.28825(25) D J /kHz 2.133(30) (1.873) 1.900(30) r c. m ./nm 44.496 ─ 44.499 K σ /(Nm -1 ) 8.14 ─ 8.51 α β /MHz ─20.07 (2) ─17.73 (27) ─18.74 (9) γ β /MHz 0.266 (4) 0.242 (36) 0.250 (17) q β /MHz 5.33 (4) 5.44 (13) 5.15 (10) α σ /MHz (31.44) ─ ─
