Sent to CCL by: "Eliac Brown" [Eliacbrown===yahoo.com] Dear All I want to use PDDG-MNDO semiempirical method in G09. According to the website, the new parameters were implemented, but I see only PDDG method, I found it uses PDDG-PM3 parameters. So, how can I use PDDG-MNDO? If it is not there, any body has the parameters file ready,please? Thanks Eliac
