Dear users,
I have run EPR parameter calculation b using ORCA which is rhombic in nature. On the output file, I am not very sure to assign which is Axx, Ayy and Azz values on the table below among -451.6, -488.39 and -606.75. I try to find from manual but unable to so. Would any one mind to o tell me which one is one? or provide the reference so that I can assign with confident and use to simulate experimental values.
Thank you so much in advance

A(Tot) -451.6467 -488.3922 -606.7515 A(iso)= -515.5968

Z -0.0000001 1.0000000 -0.0000000

The line with A(Tot) gives the three principal values of the A tensor, along X, Y and Z. The unit vectors of X, Y and Z (expressed in the coordinate system you used in the ORCA input file) are listed after that.
