Hi

I would like to find the reference which tell the bond energy.
Especially, I would like to know the pi bond energies of C=S, P=S and P=Se or their singlet-triplet excitation gaps.

CRC showed the single bond energies though.

C-Se : 590.4 KJ/mol
P-S : 444 KJ/mol
P-Se : 363.6 KJ/mol

Please help me.

It doesn't have P=Se though

Hope this helps though
