Dear all
                i want to do analytic freq. calculation of phenyl
carboxylate preceeded by optimization
after the optimization program does a single point cas calculation without
symmetry before proceeding to freq. calculation
in this this stage it gives me a strange error i dont know meaning of this
error can any one tell me how to get rid of
this proplem keeping analytic frequency calculation alive
following is the input i run

***,phenylcarboxylate radical
print,basis,orbital,civector
memory,32,m
geomtyp=xyz        ! use cartesian coordinates xmol style
