Experimental physics i & ii "junior lab", raman spectroscopy, description.
Raman spectroscopy uses the inelastic scattering of monochromatic light to probe molecular structure. In Raman scattering, the frequency of the scattered light is shifted from the frequency of the incident beam. The rotational and vibrational energy levels of the molecule in question determine the magnitude of the frequency shift. In this experiment, you will use a high powered laser scattered off of a gaseous sample to find the rotational constants of the molecules.

This module is designed to introduce the basic concepts of spectroscopy and to provide a survey of several of the most common types of spectroscopic measurement. You will conduct the following measurements. UV-VIS (ultraviolet-visible) spectroscopy of electronic states. Fluorescence spectroscopy of electronic states.
EXPERIMENT 2: INTRODUCTION TO SPECTROSCOPYIn Part One of this experiment you will be intr. duced to the fundamentals of spectroscopy. You will first learn how to properly use a Spectronic 20 instrument and then you will use the instrument to find the wavelength (λ) at which absorbance of light by a solution of food.
and describe Doppler-free saturation absorption spectroscopy of the 5S1/2 → 5P3/2 transition in rubidium, which is the simplest undergraduate experiment using a tunable laser diode [3, 4]. Afterwards, the hyperfine structure of the excited state 5D5/2 is probed using Doppler-free two-photon absorption spectroscopy.
spectroscopy to find out the chemical constitution of known and unknown gases. The same procedure is used for starlight, telling us what its source is composed of. The baseline is a laboratory experiment with known materials, and later we can compare the unknown to what we already know. Hot, glowing bodies like a light bulb, or the Sun, glow in ...

Optics and Spectroscopy Undergraduate Laboratory Resource Book. By Kevin M. Jones and Jefferson Strait. The experiments described in this book seek to illustrate basic principles of physics and their modern technological applications. As you can see, we stretched the term "Modern Optics" to include a wide variety of experiments that in one way ...

This expt. provided undergraduate students an opportunity to study important topics such as at. theory, emission spectroscopy, quant. anal., and image processing. Finally, students measured the sodium content in seawater collected from a region of the Rio Grande do Norte coast, an important region for manufg. salt.
