<br>
I have calculated the multipole moments of the ch4 molecule at hf and mp2,b=
ut in the output hf values are equal to the mp2 ones.<br>
Else: for the CH4 molecule the multipole moment of the 5th order is equal t=
o zero. here it is not zero. The hf values of octupole and hexadecapole mom=
ents are not correct at all (~5 times for hexa and ~3 times for oct mom). P=
lease, help me, what I did wrong?<br>

<br>
Best regards, Yulia<br>
