✦ Synopsis

In section 3.2 on page 445, the ratio of tautomer to normal emission intensity should be 4.2 instead of 9.52. Thus the right-hand side of the equation should be 4.2/O-41 and thus the A& should be 500 cal/mol instead of 650 cal/mol.

In table 2 the assignment of the excitation origin for the tautomer emission should be II(SII instead of III(S,)cIII(SO). *** Structure and stabilities of the isomers of SiB& (Chem. Phys. Letters 200 ( 1992) 567)
