Conformational-Dependent Photodissociation of Glycolic Acid in an Argon Matrix

چکیده
Ultraviolet-induced photodissociation and photo-isomerization of the three most stable conformers (SSC, GAC, AAT) glycolic acid are investigated in a low-temperature solid argon matrix using FTIR spectroscopy employing laser radiation with wavelengths 212 nm, 226 230 nm. The present work broadens wavelength range photochemical studies acid, thus extending understanding overall photochemistry compound. proposed kinetic model for proceeds from lowest energy conformer (SSC). suggests that ultraviolet light induces isomerization only between SSC GAC AAT conformers. relative reaction rate coefficients reported all reactions. These results suggest direct does not occur an matrix. main channel via produces formaldehyde–water complexes. mechanism emphasizes conformers’ abundancies can significantly affect molecule. For example, case high concentrations, requires proceeding to SSC.

متن کاملPhotodissociation dynamics of ionic argon pentamer.
Photodissociation of the ionized argon pentamer, Ar(5)(+), is studied using an extended diatomics-in-molecules interaction model with the inclusion of the spin-orbit coupling and various dynamical approaches. A thorough comparison with the experimental data available in the literature is presented, including photofragment abundances and their kinetic and internal energy distributions. New predi...

A Study of Surface Modification of Poly(lactic-co-glycolic) Acid Using Argon Ion Irradiation
The effect of Argon ion irradiation to the surface properties of poly(lactic-co-glycolic) acid (PLGA) was studied. A beam of 170 keV Argon ions was implanted at different fluencies (1 × 1012, 1 × 1013, 1 × 1014, and 1 × 1015 ions/cm2). X-ray photoelectron spectroscopy (XPS) was used to analyze the evolution of the bonding microstructure of PLGA due to irradiation. Surface morphology was monitor...
