Spectra for i

Figure 1 shows representative phosphorescence spectra for I, IV and XiiJ in Silicalite. In all cases emission peaks at 420 nm, and, except for the small differences in the degree of vibrational resolution the three spectra are identical.

Simulation of spectra for /i)-acacpnH2 and its trifluoro derivative indicates that the syn conformation, predominant in solution, is that having the pn methyl group anti to the N atom, as found in the solid state. A similar conformer distribution is expected also for acacenHj in view of the similarity of absorption spectra. In conclusion, it appears that these compounds exist in solution essentially in a unique conformation, maintained by strong intramolecular hydrogen bonds.

Because 3° amines have no N-H bonds, they do not absorb in this region in their IR spectra. The single bond region (> 2500 cm ) of the IR spectra for I , 2°, and 3° amines illustrates these features in Figure 25.3.
