Dihydrogen monoxide parody story has since been used in science education to encourage critical thinking and discussion of the scientific method. A 1983 April Fools' Day edition of the "Durand Express", a weekly newspaper in Durand, Michigan, reported that "dihydrogen oxide" had been found in the city's water pipes, and warned that it was fatal if inhaled, and could produce blistering vapors. The first appearance of the parody on the Internet was attributed by the "Pittsburgh Post-Gazette" to the so-called "Coalition to Ban Dihydrogen Monoxide", a parody organization at UC Santa Cruz following on-campus postings and newsgroup discussions in 1990.

Dihydrogen cation i because of the effect of the nuclear hyperfine Hamiltonian. The nuclear hyperfine Hamiltonian can mix the rotational levels of g and u electronic states (called ortho-para mixing) and give rise to ortho-para transitions The dihydrogen ion is formed in nature by the interaction of cosmic rays and the hydrogen molecule. An electron is knocked off leaving the cation behind. Cosmic ray particles have enough energy to ionize many molecules before coming to a stop. In nature the ion is destroyed by reacting with other hydrogen molecules: The ionization energy of the hydrogen molecule is 15.603 eV. The dissociation energy
