| Abstract | The strong and directional hydrogen bonding interaction between glycine (G) and nitrosamine (NA) have been investigated using B3LYP and B3PW91 methods with a wide range of basis sets. With four preferential interaction sites in the vicinity of the glycine, eight different conformations (GNA1-8) with two intermolecular hydrogen bonds [NHNA···N(O)G and O(N)NA···HXG (X = O, N, C)] were found on the potential energy surface. The influence of the hydrogen bond on the molecular and topological properties, as well as nuclear magnetic resonance one- and two-bond spin–spin coupling constants in the gas phase was investigated. The most stable complexes labeled GNA1 and GNA2 are formed in S1 site. Natural bond orbital analysis shows that in the most stable complexes GNA1 and GNA2 the charge transfer takes place from NA to G, whereas, the reverse happens in other complexes. The results predict that in all complexes, the LPO(N)NA → σ*(X–H)Gly (X = O, N, C) and LPN(O)Gly → σ*(N–H)NA donor–acceptor interactions are the most important interactions. Atom in molecule analysis confirms that all hydrogen bonds have partially covalent nature. The covalent nature of proton donor groups decreases upon complexation. The relationship between spin–spin coupling constant (1h JH···Y and 2h JH···Y) with interaction energy and electronic density at corresponding hydrogen bond critical points and H-bonds distances are investigated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
