This study comprises seven chapters. In chapter 1 an overview of chemistry, biological functions and literature studies of hydroxamic acids (HA) and its isosteres is presented. The principles of quantum mechanics underlying the computational methods employed to study HAs are given in brief. Chapter 2 describes intra- and intermolecular H-bonding interactions between formohydoxamic acid (FHA) and single water molecule and the dimerization among the isomeric forms. Chapter 3 involves the comparative study of H-bonding abilities of thioformohydoxamic acid (TFHA) and FHA. The deprotonation...

"Nibbles Goes Green" is a children's story about a bunny rabbit named Nibbles.
