Notes:
Pulsed laser optogalvanic spectra of a 32 MHz radiofrequency discharge (RFLOG) in flowing, low pressure (˜1 Torr) nitrogen are reported. The region of excitation was 16300-17300 cm-1. The observed features correspond mainly to B3Πg ← A3Σu+ transitions (Δv = 4). These are well known in emission and constitute the First Positive System that is of high intensity in almost all discharges in pure N2. A comparison of the emission, absorption, and RFLOG spectra provides an interpretation of missing and/or additional, unassigned lines that occur in the various spectra. The results indicate that RFLOG spectroscopy, as presented here, is a powerful alternative to the absorption spectroscopy of low pressure gases.
