# Calculation on the bonding energy of the Water-methanol dimer using
# the meta-hybrid based, dispersion corrected double-hybrid functional DOD-SCAN. 

# the AO-based algorithm is employed here by default, 8 numerical quadrature points
# are used for the numerical Laplace transform (as opposed to 9, which is the default). 
# For the MP2 calculation only, the Normal fitset is used, while during the SCF 
# default numerical settings are used together with the VeryGood fitset.
