It is shown that, although the shifts of Raman lines observed when random or uniaxially oriented polymers are uniaxially stressed depend on the polarization directions of the incident and scattered radiation, the shifts are not all independent. For a

The measurement of dichroic ratios in highly absorbing systems requires careful consideration of the effects of instrumental polarization sensitivity and of polarizer imperfections if accurate results are to be obtained. If the absorbances exceed abo
