Nuclear Quadrupole Hyperfine Structure in the Microwave Spectrum of Ar–N2O

Microwave spectra of eight isotopic modifications of 1-chloro-1-fluoroethylene

“…The nondeuterated isotopomers were studied in natural abundance, while the two deuterated species were synthesized at Oberlin College [4] and made available as a mixture of the two isomers in approximately 65% purity, which was used without further separation or purification. The pulsed molecular beam, Fourier transform microwave spectrometer at Amherst College has been described previously [5] and thus only few details are presented here. A 0.8 mm pulsed nozzle is mounted behind one of the mirrors that form the Fabry-Pérot cavity.…”

An ab initio potential energy surface and infrared spectra for Kr–N2O in the v3 stretching region of N2O

“…The results indicated that the complex has a T-shaped structure with the argon atom titled slightly toward the oxygen atom. Further experiments have been carried out on this complex in the microwave region with Fourier-transform microwave spectrometers [5][6][7] as well as in the infrared region with tunable diode laser spectrometers [8][9][10]. The structure of the Ar-N 2 O complex is almost unchanged upon vibrational excitation of the N 2 O-monomer v 3 (∼2224 cm −1 ) [8,9] and v 1 (∼1285 cm −1 ) [10] normal vibrational mode.…”

“…Much attention has been devoted to the interaction of rare gases with the N 2 O molecule in experimental [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and theoretical [15][16][17][18][19][20][21][22][23] studies. In experiments, the pure rotational spectra of six isotopomers of Ne-N 2 O were measured in the frequency range between 5 and 18 GHz by Ngari and Jäger using a pulsed beam cavity Fourier transform microwave spectrometer [1].…”

Infrared diode laser spectroscopy of the He–N2O van der Waals complex in the 1285cm−1 region

“…The structure of this complex was found to be nearly T-shaped with the argon atom slightly tilted toward the oxygen atom. Further experiments have been carried out on the Ar-N 2 O complex in the microwave region with Fourier-transform microwave spectrometers [2][3][4] as well as in the infrared region with tunable diode laser spectrometers [5][6][7]. Negligible structural changes were observed upon vibrational excitation of the N 2 O-monomer v 3 ($2224 cm À1 ) [5,6] and v 1 ($1285 cm À1 ) [7] vibrational mode.…”
