Abstract
An absorption spectrum in the range 200–220 nm, observed during the flash photolysis of Se2Br2, is attributed to SeBr. A vibrational analysis gives the following parameters of the states involved: X(2Πi): Te= 0 and 1070+a cm–1; ωe= 317 cm–1, ωexe= 0.7 cm–1, B: Te= 47 227 and 47 227+a cm–1; ωe= 393 cm–1, ωexe= 2.0 cm–1. An absorption spectrum due to TeI in the range 220–250 nm has been recorded in the flash photolysis of TeI2. The vibrational constants of the various states involved are: X(2Πi): Te= 0; ωe= 217 cm–1, ωexe= 0.6 cm–1. B: Te= 41 057 cm–1; ωe= 260 cm–1, ωexe= 1.4 cm–1. C: Te= 43 658 cm–1; ωe= 252 cm–1, ωexe= 0.5 cm–1.
