In this light, as the authors point out by an excellent astronomical analogy, their list of thirteen million stable compounds is actually surrounded and permeated by a huge unseen amount of “dark matter” – all those 3- and 4-membered rings.
What is the most stable isotope?
While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in nutrition research, nitrogen-15 is the most common stable isotope used in agriculture. Many other stable isotopes are also increasingly being used.
