## Abstract In a crossed laserβmolecular beam study of nitromethane it was found that the excitation of nitromethane at 266 nm did not yield dissociation products under collisionβfree conditions. When a small cluster of nitromethane was excited at the same frequency, the product was seen only at en

We report a picosecond pump-probe study of the UV photolysis of gaseous dimethylnitramine. After photolysis by picosecond laser pulses at 266 nm, efficient monophotonic collision-free photodissociation occurs within 6 ps. NO\* fragments are formed in the ground electronic state and in a fluorescent
The rotational population distribution of OD\*(A 'Z\* ) fragments produced by two-photon photodissociation of D20 at 266 nm has been determined from an analysis of the A \*x+-X 'I-I fluorescence. The distribution obtained seems to confirm the existence of long-lived trajectories when the dissociatio
The angle-velocity distribution of I(2P3/2) and I(2131/2) from photodissociation of (CH3I) n clusters was measured at 266 and 304 nm. For the monomer (n = 1), the angular distribution is very anisotropic and the translational energy spectrum is sharply peaked at high energy. For clusters (predominan
## Abstract Chromophore effect in the photodissociation of protonated peptides at 266 nm was investigated using synthetic peptides with the sequence RGGXGGGGGR where X was a phenylalanyl(F), tyrosyl(Y), cysteinyl(C), glycyl(G), seryl(S), or histidyl(H) residue. The peptides with an F or Y residue d
