Abstract

The nu ₁ and nu ₂ internal modes of the NO ₂^- radical in NaNO₂ have been studied in detail at 4 K, 77 K and 300 K. Shifts in both these modes due to isotope substitution have been observed which have enabled a complete set of force constants to be determined at all three temperatures. The isotope shifts have been calculated using a general harmonic force field, and are shown to be in excellent agreement with experimental data. Using thin samples at low temperatures it has been possible to measure shifts as low as 5 cm^-1 from the fundamental with an accuracy of+or-0.3 cm^-1.
