[molpro-user] wrong atomic ordering in Molden file

[ZOUWL]

Thanks! It seems that there are some ambiguities in the MOLDEN format: the
centers of basis functions in [MO] can be reordered according to the atoms
either in the [Atoms] section or in the [GTO] section if they don't agree.
In Molden, Gabedit, and Molpro, the latter is assumed.

Best regards,
Wenli
