Rotationally resolved infrared absorption spectrum of N+4

Abstract

Articles you may be interested in σ* resonances in electron impactinduced vibrational excitation of npropane, cyclopropane, ethylene oxide, cyclopentane, and cyclohexaneThe rotationally resolved infrared band of the antisymmetric stretching vibration ͑ 3 ͒ of N 4 ϩ has been recorded by tunable diode laser spectroscopy. A continuous supersonic expansion of pure nitrogen through a slit nozzle and electron impact ionization was employed. Forty-four P and R branch transitions with J up to 25 are observed. The band origin is at 0 ϭ2234.5084͑4͒ cm Ϫ1 and the rotational constants are determined to be B 0 ϭ0.112 05͑3͒ cm Ϫ1 and B 1 ϭ0.111 76͑3͒ cm Ϫ1 . The infrared spectrum shows that N 4 ϩ has a linear ground state structure.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] While most of the efforts were devoted to theoretical studies, the long-known existence of the stable azide anion (N 3 À ) [18] and the recent syntheses of stable salts of the pentanitrogen cation (N 5 + ) [1][2][3] have demonstrated the feasibility of experimentally pursuing polynitrogen-containing materials. The only known direct method for preparing N 5 + compounds is their synthesis from an [N 2 …”

Infrared absorption spectrum of Ar–HN2+ in a supersonic slit expansion

“…Several experimental techniques have been proposed, based either on laser flash photolysis, 2 ablation, 3 discharge, [4][5][6][7][8][9] or electron impact ionization. 10,11 Although low rotational temperatures have generally been obtained ͑typically Ͻ30 K͒, until now no weakly bound ionic complexes have been observed with these setups.…”

Mass spectrometric and laser spectroscopic characterization of a supersonic planar plasma expansion

“…2 shows that cluster ions, such as [N 2 -N 2 ] + , are formed. Such species are of particular interest for the study of charge induced intermolecular interactions [5,17,18], but an effective production has prohibited systematic spectroscopic studies of many cluster ions up to now. Signal strengths indicate cation densities of the order of 10 10 ions/cm 3 for a distance of the nozzle orifice to the skimmer of 17 mm, i.e., well above the detection limit of sensitive spectroscopic direct absorption techniques, such as cavity ring down spectroscopy.…”
