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
