dc.description.abstractSeveral $investigators^{1-3}$ have identified the $b_{1u}$ methylene wagging fundamental in crystalline polyethylene with the fairly weak infrared band observed at $1380 cm^{-1}$. The band at $1352 cm^{-1}$ was interpreted as the corresponding fundamental in amorphous polyethylene. However, recent work has shown that birth of these bands are caused exclusively, or very nearly so, by the amorphous phase. This result indicates that these hands, as well as that at $1304 cm^{-1}$, arise from twisting rather than wagging of the methylene groups. Some evidence will be given for the assumption that the $b_{1}u$ fundamental lies near $1465 cm^{-1}$ and is masked by the infrared-active methylene deformation fundamental. The strange fact that an infrared baud at $1368 cm^{-1}$, polarized in the. $b$ direction, is observed in single crystals of $n-C_{36}H_{74}$ and other n-paraffins will he discussed.en_US
