Gas-phase spectroscopy lends itself ideally to the study of isolated molecules and provides
important data for comparison with theory. In recent years, we have seen enormous …

The response of DNA and RNA bases to ultraviolet (UV) radiation has been receiving
increasing attention for a number of important reasons:(i) the selection of the building blocks …

Covering the gap between basic textbooks and over-specialized scientific publications, this
is the first reference available to describe this interdisciplinary topic for PhD students and …

Infrared laser spectroscopy is used to study the four lowest energy tautomers of guanine,
isolated in helium nanodroplets. The large number of vibrational bands observed in the …

In this work, we report on a photoionization study of the microhydration of the four DNA
bases. Gas-phase clusters of water with DNA bases [guanine (G), cytosine (C), adenine (A) …

We have simulated ionization of purine nucleic acid components in the gas phase and in a
water environment. The vertical and adiabatic ionization processes were calculated at the …

In light of a recently published study on the IR spectroscopy of guanine in He droplets (Choi,
MY; Miller, REJ Am. Chem. Soc. 2006, 128, 7320), the present letter proposes a new …

Ionization of N2O4 in and on thin water films on surfaces is believed to be a key step in the
hydrolysis of NO2 which generates HONO, a significant precursor to the OH free radical in …

Empirical, quantum chemical calculations and molecular dynamics simulations of the role of
a solvent on tautomerism of nucleic acid bases and structure and properties of nucleic acid …

The excited-state dynamics of the nucleic acid (NA) bases observed under isolated
conditions is reviewed. The photophysical properties of the NA bases are very important for …
