<p>Dear Users,</p>
<p>I was using the command mass to retrieve the masses used by molpro. However I don't understand the results.<br />The mass of carbon atoms seems to be 12.01100, while it should be exactly 12.00000, (the former seems to be the average atomic mass of the mixture of the two isotopes according to their natural abundance). What am I missing? What are the default masses actually used by molpro?</p>
<p>Thanks<br />Lello</p>
