The S[subscript N]2 reaction of 1-bromohexane and 1-bromobutane with potassium acetate is introduced to address the shortage of suitable laboratory experiments in organic laboratory. The experiment offers a review of some common laboratory techniques including the use of infrared spectroscopy to identify functional groups, the use of GC-MS…

Memory deficits produced by marijuana arise partly via interaction of the psychoactive component, [Deta][superscript 9]-tetrahydrocannabinol ([Deta][superscript 9]-THC), with cannabinoid receptors in the hippocampus. Although cannabinoids acutely reduce glutamate release and block hippocampal long-term potentiation (LTP), a potential substrate for…

The neural pathways that convey conditioned stimulus (CS) information to the cerebellum during eyeblink conditioning have not been fully delineated. It is well established that pontine mossy fiber inputs to the cerebellum convey CS-related stimulation for different sensory modalities (e.g., auditory, visual, tactile). Less is known about the…

This article describes the development and validation of the Light and Spectroscopy Concept Inventory (LSCI), a 26-item diagnostic test designed (1) to measure students' conceptual understanding of topics related to light and spectroscopy, and (2) to evaluate the effectiveness of instructional interventions in promoting meaningful learning gains…

Kinetics constitutes a core topic in both the lecture and laboratory components of lower- level chemistry courses. While textbook examples can ignore issues of time, temperature and safety, the laboratory can not. Reactions must occur slowly enough to be detected by students, occur rapidly enough for data collection in the few hours assigned to a…

Mass spectrometry is a widely used and versatile tool for scientists in many different fields. Soft ionization techniques such as matrix-assisted laser desorption/ionization (MALDI) allow for the analysis of biomolecules, polymers, and clusters. This article describes a MALDI mass spectrometry experiment designed for students in introductory…

Described are the elementary principles of Fourier transform spectroscopy and typical experimental results obtained with a modified Michelson interferometer. (RH)

Described is a device that can be set up on a bench with inexpensive apparatus. The device performs in non-coherent white light according to the laws of geometrical optics. (RH)

Describes a low-cost ($120) device which eliminates plasma lines in Raman spectra. The device consists of two prisms and two mirrors which are held in a symmetrical relationship to one another so that a particular position will allow only one wavelength to pass through on a given axis. (JN)

Presented is an introduction to the interpretation of electron spin resonance spectra of organic radicals. The article is written for undergraduate college students. (RH)

Outlined is a procedure for analyzing the ground electronic state of the iodine molecule by using information provided by "hot" bands, observed in the absorption spectrum of iodine vapor. (RH)

Outlines how the radiative properties of a surface can be tailored so as to be favorable for efficient utilization of energy. The radiative properties of concern are transmittance, reflectance, absorptance, and emittance. (JN)

A previous part (Analytical Chemistry; v57 n9 p1057A) discussed the theoretical aspects of diode ultraviolet-visual (UV-VIS) spectroscopy. This part describes the applications of diode arrays in analytical chemistry, also considering spectroelectrochemistry, high performance liquid chromatography (HPLC), HPLC data processing, stopped flow, and…
