Hi I think that I did not described my question clearly. #define ga_24 120 505 ; H - N - CH3. H, HC-6-ring, H-NT-CHn 90
three atoms A, B, C form an angle. A-B-C what does this line mean? H - N - CH3. H, HC-6-ring, H-NT-CHn 90 does it mean ? =>H - N - CH3 H - N - H, H - N - (HC-6-ring) H - N - CHn 90 (HC-6-ring) - NT -CHn CH3 - NT - CHn 90 I confuse with the comma "," and " - " what does the number " 90 " mean?
