Well yes? or do you include the protons?
Hello, thank you for replying
The molecule contain two groups (COOH), the total charge is 0
i want to make a deprotonation of the two groups (COOH) (2COOH -2H+ to obtain 2COO-). So in the new structure with two groups (COO-), when i define the charge in the gaussian 03 program , i will put -2 ? is that correct ?
Thanks in advance.
