Dear Molpro Community,
I tried to compute the expectation value of the Lsquared operator.
Now this is in essence a two electron operator, but the users manual
says that with expec,l2 it will calculate the one electron part.
In practice the program output just tells me that it will not calculate l2 at all,
since it is a two-electron operator. Is there anyone who knows a way 
around, such that I get at least the one-electron part (which is anyway
the most important part to the born-oppenheimer diagonal correction 
Thanks for your comments,
Marc van Hemert
