“…12.4) and also with a S band spectrometer (2.8 GHz). 31,55 The results obtained demonstrated a quantitative agreement between theory and experiment of the TM action. Parameters of the excited triplet state of BAPO (Scheme 12.1) were estimated from the dependence of the TM polarization versus microwave frequency.…”

“…Further details are described elsewhere. [13][14][15] Solutions of 2 (0.5 mM in label, 50 mM in PMA according to monomer concentration) in 80% aqueous buffer (acetate for pH below 5.7, phosphate for pH above ([K + ] ) 0.2 M)) and 20% methanol were used for the TR-ESR experiments. The integration window used in these studies was 400-600 ns after the laser pulse.…”

“…This is important because the position of the Dm 2 transition turns out to be relatively insensitive to the orientation of the triplet in the magnetic field, so a relatively sharp transition is observed. Figure 1 shows examples of the entire TREPR spectra of benzoin (1 a) [22] and diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (2) at 77 K [23] and the associated simulated spectra. At this temperature spin-lattice relaxation of the sublevels is of the order of a microsecond or longer.…”
