IncL Phenom 1991. II. 49. FAH spectra were acquired on a JEOL DX 303 by using a 6-8 KeV Xe primary beam and a r-nitrobenzyl alcohol matrix. The spectra reported herein were peak averaged over 4 scans losing a DA 5000 data system. The compounds reported in this paper were prepared as previously described.2 In a typical experiment, m-nitrobenzyl alcohol (1 y.~), 1 ~,LLof a 50m~ lariat ether solution (CHCls). and 1 PL of a 50 mM aqueous solution of metal chloride were carefully mixed on the FAD probe. Binding constants for the lariat ethers were determined potentiometrically in anhydrous methanol as previously described.2 hioue. Y. and Gokel, G.W.
