Studies have been conducted on the ground-state and excited-state solvolyses of the isomeric 7,8-dichloro derivatives of benzonaphthobicyclo(2.2.2)octadiene and benzoveratrobicyclo(2.2.2)octadiene. The silver ion assisted ground-state reactions proce

A series of mononuclear and binuclear gold(I) complexes containing oligo(o- or m-phenyleneethynylene) (PE) ligands, namely [PhC≡C(C(6)H(4)-1,2-C≡C)(n-1)Au(PCy(3))] (n = 2-4, 4a-c), [μ-{C≡C-(1,2-C(6)H(4)C≡C)(n)}{Au(PCy(3))}(2)] (n = 1-6, 8, 5

The photochemical decarbonylation of diphenylcyclopropenone (DPCP) to diphenylacetylene (DPA) proceeds with remarkable efficiency both in solution and in the crystalline solid state. It had been previously shown that excitation to the second electron

The initial electron-transfer reaction in photosynthetic bacterial reaction centers is the transfer of an electron from the excited state (P{sup *}) of a reactive bacteriochlorophyll dimer (P) to a bacteriopheophytin (H), generating a P{sup +}H{sup -

The lower excited states of the planar all-trans isomers of crotonaldehyde, hexadienal, and octatrienal have been investigated by multi-reference single and double excitation configuration interaction (MRD-CI) calculations. For crotonaldehyde we find

The recent isolation of fullerenes such as C{sub 60} and C{sub 70} has led to several studies of the reactivity and physical properties of their excited states. The authors recently reported that triplet C{sub 60} ({sup 3}C{sub 60}) is formed with a

Proton transfers in the ground and excited state continue to draw interest from many branches of chemistry.4 In particular, the photochemistry and photophysics of indigo (1) (Scheme 1) and its derivatives have been a matter of long-standing interest.

We report the results of picosecond and slower time scale transient absorption and emission measurements on a series of ruthenium(II) and ruthenium(III) octaethylporphyrins (Ru(OEP)(L1)(L2». The ruthenium(II) porphyrins are of three types. First are

With use of the technique of competitive collisional quenching of two-photon dissociation, the collisional quenching of photoexcited bromobenzene ions was measured for 35 neutral partners. The number of collisions required for quenching ranged from 3
