摘要：

A theoretical study of infrared photodissociation of (NO)2 is reported assuming that potential coupling induces the vibrational predissociation (VP) process. It has been observed in literature that predissociation lifetime of vibrationally excited (NO)2 shows distinctive vibrational mode specificity. We have calculated lifetimes and linewidths of the VP process. Our calculated results of lifetimes are 1.10 ns for symmetric NO stretching, and 56.3 ps for antisymmetric NO stretching. These values agree well with the corresponding experimental values (0.88 ns and 39 ps, respectively). © 1990.
