摘要：

Measurements of molecular orientation in stretched films of polydimethylsiloxane using infra-red linear dichroism have been improved by the introduction of polarization modulation of the incident electromagnetic field. This technique is able to measure small dichroic effects with high sensitivity, even for very small sample draw ratios.
