Natural nitrogen ( 7 N) consists of two stable isotopes: the vast majority (99.6%) of naturally occurring nitrogen is nitrogen-14, with the remainder being ... List of isotopes · Nitrogen-13 · Nitrogen-14 · Nitrogen-15

Isotope abundances of nitrogen. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is ...

There are two stable isotopes of N: 14 N and 15 N. Because the average abundance of 15 N in air is a very constant 0.366% (Junk and Svec, 1958), air (AIR) is ...

Variations in the isotopic composition of nitrogen in chemical reagents and natural terrestrial systems are known to exceed 200 ‰, which is much larger than the ...

Nitrogen has two stable isotopes 147N and 157N of ∼ 99.64% and ∼ 0.36% abundance, respectively. Isotope abundance variations measured for nitrogen are ...
