Phys Chem Chem Phys. 2015 Jul 15;17(29):19592-601. doi: 10.1039/c5cp03079j.

A multi-center impulsive model has been recently developed to characterize the dynamic feature of product energy distribution in photodissociation of formaldehyde, H2CO → CO + H2. (J. Phys. Chem. A, 2015, 119, 29) The model is extended to predict...

Surface chemistry of propanal, 2-propenol, and 1-propanol on Ru(001).

Physical chemistry chemical physics : PCCP

Esan DA, Trenary M.

Indian J Dermatol Venereol Leprol. 1987 Mar-Apr;53(2):103-107.

Sixty four patients (40 males, 24females) of contact dermatitis of hands were patch tested. The patients included housewives (22), factory workers (16), office workers (8), medical and para - medical personnel (8), building workers (3), teachers (4), and photographer,...

Brute Force Orientation of Matrix-Isolated Molecules: Reversible Reorientation of Formaldehyde in an Argon Matrix toward Perfect Alignment.

Angewandte Chemie (International ed. in English)

Park Y, Kang H, Kang H.
PMID: 27996190
Angew Chem Int Ed Engl. 2017 Jan 19;56(4):1046-1049. doi: 10.1002/anie.201610948. Epub 2016 Dec 20.

Brute force orientation by an electric field is a promising way of controlling the orientation of polar molecules in the gas phase, but its application to condensed-phase molecules has been very limited. We studied the reorientation of formaldehyde molecules...
