Ab initio calculations and atoms-in-molecules (AIM) analysis have been used to investigate the host-guest interaction in dodecahedral water cages using a variety of guest species that include monatomic (He, Ne, Ar, Kr, and Xe), diatomic (CO, H(2), N(2), O(2),...

Radiative lifetimes of spin forbidden a1Δ → X3Σ- and spin allowed A3Π → X3Σ- transitions and complete basis set extrapolated ab initio potential energy curves for the ground and excited states of CH-.

PMID: 23231238
J Chem Phys. 2012 Dec 07;137(21):214314. doi: 10.1063/1.4768873.

The spin forbidden transition a(1)Δ → X(3)Σ(-) in CH(-) has been studied using the Breit-Pauli Hamiltonian for a large number of geometries. This transition acquires intensity through spin-orbit coupling with singlet and triplet Π states. The transition moment matrix...

Ab initio quantum chemical investigation of the ground and excited states of salicylic acid dimer.

The journal of physical chemistry. A

Maheshwary S, Lourderaj U, Sathyamurthy N.
PMID: 17107118

The structure and stability of different forms of salicylic acid dimer have been examined by Hartree-Fock and density functional theoretic calculations using 6-31G(d,p) and 6-311++g(d,p) basis sets. Vertical excitation energies for the monomer as well as the dimer have...

Beta-phenyl quenching of triplet excited ketones: how critical is the geometry for deactivation?.

The Journal of organic chemistry

Samanta S, Mishra BK, Pace TC, Sathyamurthy N, Bohne C, Moorthy JN.
PMID: 16749774
J Org Chem. 2006 Jun 09;71(12):4453-9. doi: 10.1021/jo060200e.

The phenomenon of beta-phenyl quenching has been examined by laser-flash photolysis in a series of alpha- and/or beta-substituted ketones 4-8 with similar excited-state characteristics. It is found that alpha-substitution markedly increases the triplet lifetimes in contrast to beta-substitution. The...

Three dimensional quantum dynamics of (H-, H2) and its isotopic variants.
