摘要：

Photoelectron spectra of the BN- anion at 266 nm and 355 nm are reported. We observe transitions to the ground and three lowest excited states of BN. The electron affinity of BN (X(3)Pi) is 3.160 +/- 0.005 eV. Spectroscopic constants for the anion (X(2)Sigma(+)) are r(e) = 1.284 +/- 0.005 Angstrom, omega(e) = 1660 +/- 40 cm(-1) and omega(e)chi(e) = 12 +/- 4 cm(-1). Term energies T-0 for the excited states of BN are 0.031 +/- 0.004 eV (a(1)Sigma(+)), 0.468 +/- 0.004 eV (b(1)Pi) and 1.221 +/- 0.006 eV (A(3)Sigma(+)). (C) 1998 Published by Elsevier Science B.V.
