Abstract
Six bands of the b1Σ+–X3Σ− transition of the PBr molecule have been observed in a microwave discharge of PBr3 + He. High resolution spectra have allowed the rotational analysis of the 0–0 and 1–1 bands. The principal molecular constants obtained are:X3Σ−: P79Br; ωe = 458.35 cm−1, Be = 0.16067 cm−1; P81Br; ωe = 457.78 cm−1, Be = 0.15958 cm−1; re = 2.1714 Å.B1Σ+: P79Br; ωe = 485.47 cm−1, Be = 0.16509 cm−1; P81Br; ωe = 483.84 cm−1, Be = 0.16399 cm−1; re = 2.1421 Å and Te = 11779.75 cm−1.Keywords
