Hello  Isogeochemists -


Can someone please recommend  methods for preparing and measuring the dD of
both the total H's and non-exchangeable (alkanoic) H's of
low-molecular-weight fatty acids (~C2-C6)?  I suppose that the dD of the
total H's would be via an H20-equilibration method and that the
non-exchangeable H's would be measured after derivatizing the carboxyl -O-H.
Is that right?  What kind of derivatives should be used?  I would appreciate
your help.


Although I looked in the ISOGEOCHEM archive, I couldn't find anything on
these topics. 


Thanks in Advance,

John J.
