Example: spin-orbit coupled MP2: atomization energy I2

Download I2_SO_MP2.run

#!/bin/sh

# MP2 results are calculated for I2 and the open shell atom I, such
# that the atomization energy of I2 can be calculated.
# The relativistic RA-X2C method is used and spin-orbit coupling is included.

# Remark: the atomization energy will be almost the same if one would compare
# the results for the relativistic methods ZORA, X2C, and RA-X2C in case
# spin-orbit coupling is included.
