Abstract:The infrared and electronic absorption spectra of semicarbazide
hydrochloride and its complexes with anthracene,
tetracyanoquinodimethane TCNQ, Na-fluorescein and cupferron were
recorded in the regions 200–4000cm-1 and
200–400nm. The new bands that appeared in the complex spectra
were assigned. The effect of the complex formation on the frequency
and intensity of the active vibrational bands was also studied. The
internal energy changes of the complexes were calculated in a new line
of calculation to give a cl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
