Abstract :
A modification to a Perkin-Elmer model 521 infrared spectrophotometer is described which allows a difference spectrum to be obtained from the same sample of a nerve between resting and excited states. Signal processing using time averaging and digital smoothing are employed to improve the signal-to-noise ratio (S/N).
