Spectroscopy of Sound Transmission in Solid Samples
Campbell, Dean J.; Peterson, Joshua P.; Fitzjarrald, Tamara J.
Journal of Chemical Education, v91 n19 p1684-1688 Oct 2013
These laboratory experiments are designed to familiarize students with concepts of spectroscopy by using sound waves. Topics covered in these experiments include the structure of nitinol alloys and polymer chain stiffness as a function of structure and temperature. Generally, substances that are stiffer or have higher symmetry at the molecular level transmit sound more effectively, and the higher pitched sounds that they produce upon impact can be heard and visually observed using a laptop microphone and SpectrumView freeware. This lab is designed for use in an introductory undergraduate chemistry course, although the techniques can be used for more and less advanced courses. Additional related classroom demonstrations are also presented.
