On February 15, 2022, Misaela, Francisco-Marquez; Alexander, Perez de la Luz; Catalina, Soriano-Correa; Carolina, Barrientos-Salcedo; Ignacio, Sainz-Diaz C. published an article.Formula: C8H10N2O3S The title of the article was Tautomerism and IR spectroscopy of arylsulfonamides by quantum mechanical calculations. And the article contained the following:
The mol. structures of sulfonamides are interesting for evaluating their mobility in soils and preparing composite complexes for optimizing the use of these drugs. In this work, the mol. structures of several arylsulfonamides along with conformational anal. and tautomerism were investigated theor. The spectroscopical properties of several arylsulfonamides, were also studied at mol. level by using a computational modeling at quantum mechanics level. Besides, the controversial exptl. results found in the IR (IR) spectroscopy bands assignments of solid sulfonamides pushed us up to study computationally the crystal structure of sulfamethazine for clarifying previous assignment discrepancies. The previously proposed polymorphism in the crystal structure of this drug has been also clarified in this work. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Formula: C8H10N2O3S
