Dear CClers,

 This question has been postet already in this list but i could not find 
an answer in the archives (sorry if indeed the answer was there!)

 I am trying to do a frequency calculation with the option Hindrot in a 
five-member ring system but the job ends with the (known) error message:

            Hindered Internal Rotation
 Analysis Internal coordinate list checked
 Check for planar centers
 Check reduced barrier height. Cut-off : V/RT = 33.7561
 Check for ring deformation
 Number of internal rotation degrees of freedom = 0
 NNew= 33 NTest= 0 NB= 5 IFrz= 0 IBar= 0 ICyc= 0
  Problem with the number of degrees of freedom

 Is it possible to overcome this problem somehow?

 Thank you in advance,

 Victor Rayon
