Rotational spectrum of cis-cis HOONO.
The pure rotational spectrum of cis-cis peroxynitrous acid, HOONO, has been observed. Over 220 transitions, sampling states up to J'=67 and Ka'=31, have been fitted with an rms uncertainty of 48.4 kHz. The experimentally determined rotational constants agree well with ab initio values for the cis-cis conformer, a five-membered ring formed by intramolecular hydrogen bonding. The small, positive ...
متن کاملRotational spectrum of tryptophan.
The rotational spectrum of the natural amino acid tryptophan has been observed for the first time using a combination of laser ablation, molecular beams, and Fourier transform microwave spectroscopy. Independent analysis of the rotational spectra of individual conformers has conducted to a definitive identification of two different conformers of tryptophan, with one of the observed conformers n...
متن کاملRotational spectroscopy and dipole moment of cis-cis HOONO and DOONO.
The rotational spectrum of cis-cis HOONO has been studied over a broad range of frequencies, 13-840 GHz, using pulsed beam Fourier-transform microwave spectroscopy and room-temperature flow cell submillimeter spectroscopy. The rotational spectrum of the deuterated isotopomer, cis-cis DOONO, has been studied over a subset of this range, 84-640 GHz. Improved spectroscopic constants have been dete...
متن کاملThe rotational spectrum of CN-.
The rotational spectrum of the molecular negative ion CN(-) has been detected in the laboratory at high resolution. The four lowest transitions were observed in a low pressure glow discharge through C(2)N(2) and N(2). Conclusive evidence for the identification was provided by well-resolved nitrogen quadrupole hyperfine structure in the lowest rotational transition, and a measurable Doppler shif...
متن کاملRotational Spectrum of cis-HS3D
In our pursuit of understanding the structure of sulfur chain molecules we have extended our investigations on the rotational spectrum of HSSSH [1, 2] to the partially deuterated species HSSSD. The rotational spectrum of HSSSH was found to be dense, and the carrier of the strongest absorption lines assigned at that time was the cis-conformer of HSSSH, displaying a strong c-type spectrum. Since ...
