Hai CCL'ers
	Could anyone help me in finding the experimentally assigned force constants
for the five-membered heterocycles, Furan, Thiophene and Pyrole.  Any references to
comparison with theoretical calculations are most welcome.
	By the way, is there any freeware that interprets/assigns the characteristic
normal-mode (as to whether it is a C-C or a C-H stretching or C-C-X bending, wagging
etc.) from gaussian outputs.
	I will summarise the responses if there is sufficient interest.  Thanks.
