Since the PPCHTeX mailing list (ntg-ppchtex@ntg.nl) seems to be inactive, I'm posting to the present list my PPCHTeX question.

Suppose I have the following PPCHTeX code:

\startchemical \chemical[SIX,ROT2,B,R36,RZ6][CH_3] \chemical[PB:RZ3,ONE,Z05,SB5,EP37,PE][O,H] \stopchemical

. Now, if I want `size' to be `big' but `scale' to be `small', I just type:

\startchemical[size=big,scale=small]

et cetera, but then I have a problem: the two couples of electrons that are above and under the oxygen atom come much too close the oxygen atom, they come onto it. Is there any PPCHTeX user that knows if it's possible to avoid that, and how?

The solution came from Hans Hagen, the author of PPCHTeX, who kindly provided himself some additional code. So, if anybody has the same problem, just write to me (or to Hans Hagen) and I will sent it to him/her. Thanks, Rodolfo
