Absorption Bands of Carbon Dioxide from 28–42 μ

The high-resolution spectrum of CO2 has been studied between 2.8 and 4.2 μ, by using up to 48 meter-atmospheres path to develop weak bands. Accurate band constants have been obtained for the transitions 1310–000, 0510–000, and 101–0200, and fragments of new weak bands have been detected near 3500 cm−1. Estimates of band intensities are given, including a discussion of the highly abnormal intensity distribution in the weak perpendicular bands.
