Abstract
The deactivation of the S-1(pi,pi*) excited state of nickel tetraphenylporp hine has been investigated using various transient grating techniques. By m easuring the density changes of the sample occurring during this process, t he excited state, that is responsible for the ground state recovery time of 250 ps, was determined to lie 1.18 +/- 0.13 eV above the ground state. Thi s value suggests that this slate is the (1)(d,d) state. (C) 1999 Elsevier S cience B.V. All rights reserved.
