Amber Listserv / the baltic shoulder curve

[David Cross]

Hi Hans,
The "Baltic Shoulder" is shown in both Andrew Ross's book "Amber" (Page 9) and Weitschat and Wichard's "Atlas of Plants and Animals in Baltic Amber" (page 16) to be around the 1200 /cm region. Don't know if this helps.
Dave on Oz.

  I'm looking for somebody who can perform a test on a slice of amber for me, to proove that it is real Baltic amber, and not dominican.
  David Grimaldi writes me concerning this technique: > The Baltic amber (succinic acid) shoulder is readily recognizable in FTIR,
  > and in pyrolyis GC as well. "
  However, I don't know where in wich wavelength range the 'Baltic shoulder curve' should be visualized. Who can help me?
  Hans
