Nitrogen 15

Nitrogen 15 accounts for 0.364% of all nitrogen on the earth in one of the stable isotopes of naturally occurring nitrogen. I am comprised of seven protons and neutron eight.

Nuclear magnetic resonance

A main use of nitrogen 15 includes the use as the observation nucleus in Kobo for a nuclear magnetic resonance. Because a spin is 1, as for nitrogen 14 which exists most as an isotope of nitrogen naturally, there is ends of the earth child interaction and is hard to get the spectrum which therefore is high resolution. On the other hand, a spin is -1/2, and nitrogen 15 does not have ends of the earth child interaction, and the spectrum which is high resolution is provided. Therefore I observe nitrogen 15 when I measure nitrogen in many cases [¹].
