Ab Initio Ionization Energy Thresholds of DNA and RNA Bases in Gas Phase and in Aqueous Solution
Carlos E. Crespo-Hernández,Rafael Arce,Yasuyuki Ishikawa,Leonid Gorb,Jerzy Leszczynski,David M. Close +5 more
TL;DR: Ionization energy thresholds for the canonical DNA and RNA bases both in the gas phase and in aqueous solution at HF and MP2 levels of theory using standard 6-31++G(d,p) basis were calculated in this article.

Photochemistry of pyrene on unactivated and activated silica surfaces
Celso A. Reyes,Myriam Medina,Carlos E. Crespo-Hernández,Mayra Z. Cedeno,Rafael Arce,Osvaldo Rosario,Daniel M. Steffenson,Ilia N. Ivanov,Michael E. Sigman,Reza Dabestani +9 more
TL;DR: In this article, photolysis of pyrene at the solid/air interface of unactivated and activated silica gel proceeds slowly to give mainly oxidized pyrene products, including 1-hydroxypyrene, 1,6-pyrenedione, and 1,8 pyrenedion.

Photochemical Transformations of Benzo[e]pyrene in Solution and Adsorbed on Silica Gel and Alumina Surfaces
Silvina E. Fioressi,Rafael Arce +1 more
TL;DR: The photodegradation of benzo[e]pyrene (BeP), a ubiquitous polycyclic aromatic hydrocarbon (PAH) contaminant, was investigated in solution and adsorbed on surfaces modeling the atmospheric particulate matter to provide fundamental information that could help to clarify its fate in the atmosphere.

Spectroscopy and photochemistry of fluorene at a silica gel/air interface
TL;DR: In this article, an electron transfer oxidation mechanism was proposed to account for the observed photochemical oxidation of fluorene at the silica gel/air interface by transient diffuse reflectance spectroscopy.

Photochemistry of acenaphthene at a silica gel/air interface
TL;DR: In this article, the photolysis of acenapthene (ACE) has been studied at a silica gel/air interface and the reaction leading to formation of both 1-acenaphthenol and 1-acethenone are attributed to electron-transfer oxidation mechanisms.
