Presents the spectra of the flames of three gaseous mixtures, together with analyses of the rotational, vibrational, and electronic contributions to the spectra. (MLH)

Describes a demonstration technique for showing multiple-slit interference patterns with the use of a Fabry-Perot etalon and a laser beam. A simple derivation of the analytical expression for such fringes is presented. (Author/CP)

Presents a simple method of analysis in which the student can integrate, point by point, any interferogram to obtain its Fourier transform. The manual technique requires no special equipment and is based on relationships that most undergraduate physics students can derive from the Fourier integral equations. (Author/MLH)

This is a textbook of Fourier optics for the classroom or self-study. Major topics included in the 38 chapters are: Huygens' principle and Fourier transforms; image formation; optical coherence theory; coherent imaging; image analysis; coherent noise; interferometry; holography; communication theory techniques; analog optical computing; phase…

Presents a summary of the state of the field in instrumentation as it existed in 1940-1941 as described in articles written at that time by R. H. Muller. (SLH)

Describes a series of experiments designed for general chemistry in which the students prepare metal complexes which are then used as samples for spectral study. (SLH)

Describes a simple method, the Edser-Butler methods, for calibrating the Fabry-Pevot fringes seen in the focal plane of a spectrograph. (GA)

Describes the current understanding of the structure and evolution of the white dwarf stars that was gained as a result of the increasingly sensitive and detailed astronomical observations coupled with calculations of the properties of matter under extreme conditions. (Author/GA)

Describes an instructional experiment that was designed to illustrate the use of periodate oxidation in sugar analysis, and the consequence that the absorbance of mixtures of non-interacting substances is additive. (TW)

Described is a laboratory exercise that uses nuclear magnetic resonance to monitor enantiomeric excess in asymmetric reductions. The laboratory exercise has been used successfully with undergraduate organic chemistry students. (RH)

The construction of a diffraction grating spectroscope has been previously reported. A procedure to fit a linear scale to this spectroscope is described (allowing measurement on wavelength of spectral lines without increasing cost of the assembly). Also described are some applications of this modified spectroscope for secondary school laboratory…
