(1998)The infrared spectra of naphthalocyanine (H2Nc) and its copper(II) complex (CuNc) were registered in the region 4000-450 cm-1. These compounds were deposited onto a smooth copper surface and their specular infrared spectra ...
-
(Marcel Dekker. Inc., 1987-04-11)Thymine dimers were obtained under ultraviolet irradiation. The major product is a trans-anti dimer linked by a cyclobutane ring. The infrared assignments and the mechanism of formation of this dimer are discussed in ...
-
(EDP Sciences, 2015)Context. Infrared dark clouds are the coldest and densest portions of giant molecular clouds. The most massive ones represent some of the most likely birthplaces for the next generation of massive stars in the Milky Way. ...
