Infrared Spectrum of Hydrogen Sulfide from 2200–2800 cm−1

The absorption of hydrogen sulfide from 2200 to 2800 cm−1 has been observed under high resolution. It can be accounted for by two bands having excited states (n1,n2,n3) = (0,2,0), and (1,0,0). A novel feature of this analysis is the assignment of the strong absorption in the high-frequency portion of this region as arising from the transition (0,0,0)→(1,0,0). The parameters giving the best fits to the observed absorption are: A*B*C*ν0(0,2,0)11.0999.4434.6102353.93 cm−1(1,0,0)10.2498.8314.6632614.56 cm−1.It was not possible to assign enough transitions in the (0,0,1) band to determine a unique set of parameters.
