| Abstract | Periodic first-principle calculations have been performed to study the effects of electric field on the geometric and electronic structures and decomposition mechanism of crystalline zinc carbohydrazide perchlorate (ZnCP). The results show that the influences of external electric field on the crystal and molecular structures are very weak and ZnCP does not undergo a phase transition at an applied field smaller than 7.492 V nm−1. Moreover, the ionic coordination bonds are more susceptible to the electric field mainly because of their weak interatomic interactions as compared to the stronger covalent bonds. In addition, the applied field across the crystal develops instabilities and ZnCP is more sensitive to the field than lead styphnate. At an electric field of 7.492 V nm−1, ZnCP has metallic properties. Interestingly, the electric field redistributes the electron density of the frontier molecular orbitals, but the decomposition mechanism of ZnCP in the presence and absence of the field is similar. Finally, the electric-field-induced decomposition of ZnCP produces many gases and the final decomposed residue is ZnO. |

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.
