The submillimeter-wave spectrum of diisocyanomethane. (2012)

Keywords : ISM molecules - methods: laboratory - submillimeter: ISM - molecular data - line: identification

Abstract:Several organic isocyanides have been observed so far in ISM (HNC, CH_3_NC, HCCNC). However there is still a lack of high-resolution spectroscopic data on simple iso- cyanides that could provide a basis for their detection. Diisocyanomethane (NC-CH_2_-CN) is a small molecule having only 7 atoms and being an interesting candidate for astrophysical detection. Rotational spectrum of diisocyanomethane has never been studied before. We measured the rotational spectrum of diisocyanomethane in the ...(more)
Abstract: (hide)
More than 2000 lines of the ground and first excited vibrational state of diisocyanomethane were measured in the frequency range 120-620GHz. They are listed in the tables. The molecule is an asymmetric top and the fits were performed using Watson's A- and S-reduction Hamiltonians in Ir representation. The tables contain line assignments, observed frequencies, residuals of the fits using A and S-reductions and accuracy of frequency measurement.
