Nitrogen

Table 1. Nitrogen 1s binding energy values [1].

a) The binding energy values for nitrogen in organic compounds overlap significantly and can be difficult to decipher especially if there are multiple nitrogen containing groups. An excellent resource is Appendix 4 in the "High Resolution XPS of Organic Polymers - The Scienta ESCA300 Database"[2].
