Heterocyclic Compounds

The Wide Spread application of Heterocyclic compounds in material science has driven the development of Theoretical Investigations of Hetero Cyclic Compounds. Among the most exciting tools for the analytical chemist and biochemist are the modern spectrographs which are proficient of providing structural as well as compositional information in relation to compounds. In organic chemistry, Hetero cyclic chemistry is one of the most fascinating branches. Hetero cyclic compounds be similar to cyclic organic compounds due to the presence of the hetero atoms, the heterocyclic compounds have physical and chemical properties that are unique from that of those of all carbon ring analogs. Heterocyclic compounds present a high degree of structural assortment

Imidazoline derivatives are biologically and pharmaceutically incredibly important such as anti-inflammatory [22], antihypertensive [23] etc. The imidazoline drugs are utilized for remedying of the high blood pressure with the combination of supplementary medicines. Oxozolone are heterocyclic compounds also referred as 5(4H)-Oxazolone .Hetero cyclic compounds containing oxozolones are important targets in synthetic and Medicinal chemistry, because of their significance as potentially active compounds [24–28]. The photo physical properties of oxozolone derivatives are important for potential applications in photonics and electronics [29, 30]. Rhodanine is a heterocyclic compound having various applications in chemistry, biochemistry and biology etc. Recent studies proved that this type of molecular framework is remarkable for its potential in the design and synthesis of non-linear optical (NLO) materials [31, 32], due to their large molecular hyperpolarizabilities and asymmetric charge distribution. Chemical properties of Rhodanine and its derivatives are of interest due to coordination capacity and their use as metal extracting agents and as analytical reagents [33,

Vibrational spectroscopy, Nuclear magnetic resonance (NMR), Fluorescence etc., has played a significant role in the development of various spectroscopic techniques. In the past two decades quantum chemical computational
Methods have proven to be an essential tool for interpreting and predicting vibrational spectra [b,
