Thymol ir spectrum
Webb摘要： Thymol (Thy) is a widely known anti-microbial agent and can be found as one of the components of many essential oils. Intermolecular charge-transfer complexes between the Thy as a donor and picric acid (PA), chloranilic acid (CLA), 1,3-dinitrobenzene (DNB) or p -chloranil ( p -CHL) as a p-acceptor have been structurally and thermally studied in … WebbThe chemical interactions and functional groups of thymol, thymol nanoparticles and PVA were studied using FTIR spectroscopy (Fig. S1). In the FTIR spectrum of thymol, …
