Ab-initio and thermodynamic study of 123I-MIBG and 76Br-MBBG : choosing an effective tracer and theoretical study of the binding mechanism of 1-allyl 2-Thiourea as a functional monomer of Methyl Nitrate template
The study of mechanisms of reactions, how molecules bind, reaction energetics, and thermochemistry of chemical reactions is possible computationally. This is because computational methods are well able to help understand and also describe the dynamics of chemical bonding -- forming and breaking of …
