Dihydrogen monoxide parody oxygen atom. Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix "" in "dihydrogen" means "two", the prefix "" in "monoxide" means "one", and an oxide is an oxygen atom attached to another atom in an ionic compound. Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include "hydrogen oxide", as well as an alkali name of "hydrogen hydroxide", and several acid names such as "hydric acid", "hydroxic acid", "hydroxyl acid", and "hydroxilic acid". The term "hydroxyl acid" used in the original text
Dihydrogen bond a normal N−H vibration whereas the lower energy band is assigned to the same bond, which is interacting with the B−H. Upon dilution of the solution, the 3300 cm band increased in intensity and the 3210 cm band decreased, indicative of intermolecular association. Interest in dihydrogen bonding was reignited upon the crystallographic characterization of the molecule HNBH. In this molecule, like the one studied by Brown and Hazeltine, the hydrogen atoms on nitrogen have a partial positive charge, denoted H, and the hydrogen atoms on boron have a partial negative charge, often denoted H. In other words, the amine is
