Infrared spectrum of isotopic carbon dioxide in the region of bending fundamental ν2

Infrared absorption spectra of ¹³C¹⁶O₂, ¹³C¹⁸O₂, ¹⁶O¹³C¹⁷O, ¹⁶O¹³C¹⁸O, and ¹⁶O¹²C¹⁸O have been measured in the wavenumber region 570–780 cm^?1 with a spectral resolution of about 0.005 cm^?1. The data were recorded at room temperature with a Fourier transform spectrometer using a ¹³C-enriched sample of carbon dioxide. The fundamentals ν₂ and several “hot” bands have been identified and effective molecular constants have been derived.
