✦ Synopsis

The microwave spectrum of 1-fluoropropyne (\left(\mathrm{CH}{3} \mathrm{CCF}\right)) has been detected for the first time in the discharge plasma of 2,3,4.5,6-pentafluorotoluene (\left(\mathrm{CH}{3} \mathrm{C}{6} \mathrm{~F}{5}\right)). Rotational transitions of (\mathrm{CH}{3} \mathrm{CCF}) with (J=30-29) to (38-37) were measured in the region between 207 and (262 \mathrm{GHz}). The accurate molecular constants were determined to be (B=3451.46584(30) \mathrm{MHz}, D{J}=0.34071(13)) (\mathrm{kHz}), and (D_{J K}=43.090(11) \mathrm{kHz}), where the uncertainties correspond to one standard deviation.

trans-1-Nitrosopropene (syn form) was generated in the gas phase by pyrolysis of 1-chloro-1-methyl-2-(hydroxyimino)ethane and identified by microwave spectroscopy. The microwave spectrum of the pyrolysate was observed in the frequency range from 8.0 to 40.0 GHz. The rotational constants (MHz) were d
