The route section of my job reads: %NProcShared=20 %mem=42gb # opt freq aug-cc-pvtz polar qcisd The job fails with an error which can be seen from the bottom of output below: Iteration Nr. 12 ********************** DD1Dir will call FoFMem 1 times, MxPair= 56 NAB= 20 NAA= 10 NBB= 6. DE(Z) -0.28201232D+00 E(Z)= -0.11475119242D+03 NORM(A)= 0.10305469D+01 Discarding MO integrals.

Write -1 instead of 1500424200. fd = 4 orig len = 1500424200 left = 1500424200 g_write Any help to resolve this problem will be appreciated. Also, can i obtain polarizability and hyperpolarizabity at QCISD method by keywords given as above? Thanks in advance!
