Before examining what a molecular orbital is, it is good to refresh our memories with respect to the types of bonding that can occur between atoms when molecules are formed. Basically there are two prevalent types of bonding that occur in organic chemistry. (There are several ways that bonding can occur but most of these ways can be classified into two very broad categories.) The first category...

We have no hesitation in recommending this Treatise on Plague by Dr. W. J. Simpson as the most complete and comprehensive volume dealing with the subject which has yet seen the light.
