Spectrochemical Analysis
CHEM 529
Spring, 1999



Time:10:30-11:20 AM MWF
Place:CB 205
Professor:Dr. Gary Rayson
Office hours:By Appointment
Office:CB 289



Texts: Spectrochemical Analysis, J. D. Ingle, Jr., and S. R. Crouch and Focus on Analytical Spectrometry, J. A. Holcombe, G. M. Hieftje and V. Majidi.

Lecture Notes: Copies of "some" of the referenced literature will be available.

Course Objective:
The objective of this course is to familiarize the student with the details of the workings of spectrochemical methods of analysis to enable informed decision to be made in the design and execution of techniques for the analysis of samples using spectroscopic measurements.

Grading and Exams:
Three (3) exams will be given during the semester. A comprehensive exam will be given during the scheduled final exam period. The final will be weighted as one exam. The lowest exam score of the four (4) total will be replaced by the next lowest score. A library research paper will also be required. This paper will be on a topic of current relevance in the area of spectrochemical analysis. All topics must be pre-approved by the instructor prior to February 28. The format for the paper will be that of the journal Analytical Chemistry. This can be found in the Information for Authors found in the January 1 issue. Alternately, the ACS Style Guide may be used for questions of style and format. All papers will be due no later than 5:00 PM on the last day of classes (prior to Finals Week). The paper will be counted as the equivalent of one exam score (20% of the total). The course grading scale will be determined based on the total class performance on the examinations and the resulting distribution of those scores. Grades will not be assigned for individual exams or the paper.

Students with Disabilities. If you have or believe you have a disability, you may wish to self-identify. You can do so by providing documentation to the Office for Services for Students with Disabilities (phone: 656-6840). Appropriate accommodations may then be provided for you.

If you have a condition which may affect your ability to exit safely from the premises in an emergency or which may cause en emergency during class, you are encouraged to discuss this in confidence with the instructor and/or the director of the Office for Services for Students with Disabilities. If you have general questions about the Americans with Disabilities Act (ADA), call the Interim ADA Coordinator at 646-3635.
