Abstract

The adaptation of the surface laser light scattering research method to an advanced undergraduate physical chemistry, polymer chemistry, or materials science laboratory is described. The SLS method was made accessible to an undergraduate setting by replacing the spectrum analyzer or autocorrelator normally used for data acquisition with a relatively inexpensive digital oscilloscope. A comparison between data obtained with a digital oscilloscope and with a spectrum analyzer is presented for the packing of a polymer film on a water substrate.
