This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a bimodal sample containing two different length PTAA chains (n=10 and 80) and a monomdal sample (n=10). It was found that the ALCs width and amplitudes were different for the two samples, which was probably due to the distribution of local order within the PTAA. For this proposal we would like to study the ALCs of as a function of temperature of a monomodal n=80 PTAA sample, to complete the study and compare with the bimodal and monomodal data.
