Hi,
Thank you all the repliers who kindly offer their hands after my
PREVIOUS posting message. I received around 12 messages in total and the
concensus reply is:
P422 POINT GROUP WITH ONLY ONE MOLECULE IN ONE A.U.(peak (90 45 180)
indicates P422 with the 2-fold crystallographic symmetry along the
diagonal. The 4-fold symmetry is at the origin along C axis).
Hope this will help to my peers who has the similar wanderings.
Thanks you again.
