Photoionization of Vibrationally Excited Nitrogen.
Abstract
A quadrupole mass spectrometer with a photoionization source has been used in conjunction with a flowing nitrogen afterflow to obtain the photoionization spectrum of vibrationally excited nitrogen (N2*) at a spectral resolution of 0.03 nm in the interval 79.58 - 84.20 nm. This wavelength interval lies below the photoionization threshold of N2 (v '' = 0). More than 50 new preionized bands and an underlying continuum have been observed. From estimates of the concentrations of various vibrationally excited states of N2 and measurements of the ionizing photon flux as a function of wavelength, the authors have estimated the photoionization coefficients of the new preionized bands and continuum.
