Abstract

Abstract Spectroscopic properties of 4‑hydroxy carbazole have been characterized by analytical spectroscopic techniques with help of high level quantum chemical calculations. For the structural confirmation and to gain better insight on 4‑hydroxy carbazole, the structural properties, vibrational assignments, chemical shifts, electronic properties and other molecular parameters were determined and comprehensively discussed. The molecular electrostatic potential surfaces (MESP) have been generated to isolate the reactive sites for electron rich and electron poor regions in this compound, and additionally confirmed with Mullikan atomic charge distribution analysis. The obtained experimental and theoretical results show an excellent correlation to confirm the molecular structure of 4‑hydroxy carbazole.
