Natural Bond Orbital Analysis

NBO 1 is a bond between the atoms C 1 and N 2 resulting from the overlap of an sp^3.61 hybrid on C with an sp^2.24 hybrid on N.

s_CN = 0.633(sp^3.61)_C + 0.774(sp^2.24)_N

The higher electronegativity of the N 2 atom is reflected in the larger polarization coefficient (0.774) for the N hybrid.
