Abstract:
The 0-1 band (4271.3 Å) of the B(2)Sigma(+)-X(2)(2)Pi(3/2) transition, the 0-6 band (4275 Å) of the H(2)Pi(3/2)-X(2)(2)Pi(3/2) transition, the 0-0 band (3776.2 Å) of the B(2)Sigma(+)-X(1)(2)Pi(1/2) transition, and the 2-0 (3251.3 Å) as well as the 3-0 (3194.2 Å) bands of the C(2)Sigma(-)-X(1)(2)Pi(1/2) transition of SbO have been photographed at high resolution using the single isotope of antimony (121)Sb. An unambiguous analysis of the rotational structure of all these bands has been carried out for the first time. The magnitude and sign of the Lambda doubling constant p(0) of the X(1)(2)Pi(1/2) state have been determined and as a result of that, the symmetry of the C state has been uniquely identified as C(2)Sigma(-). Accurate rotational constants of all the states involved have been determined by a global linear least-squares fit. Copyright 2000 Academic Press.

Radicals: Electronic Structure and Geometry
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
