Alignment kinetics as a function of temperature. (A) The kinetics of the alignment process as a function of time. Data were collected for one peptide sample at 35°C (▪), 45°C (○), and 55°C (crosses) and have been normalized for the slight variation in area of amide I′ band. Lines through the data points represent the stretched exponential fits to the data. Kinetic measurements were also taken at 40°C and 50°C (data not shown). All five data sets confirm the hypothesis that the alignment process increases in rate as temperature increases. (B) An Arrhenius plot was constructed for each set of temperature-dependent kinetic results. The linear fit confirms the Arrhenius-type behavior of the kinetics. Activation energy was calculated from the gradient of the line.
