trbx ~&elf.If thus is so, rt extends the range of surfaceenhanced techmques to msoluble as well as soluble speties. in any event, there is no evidence of chermcai reactron on pressing the discs, and they are robust and easily handled so that hip-resolutton Raman spectra of insoluble copper phthalocyanmes are now accessrble by this sample evtensron to existmg techniques.
