Analytical Chemistry at Widener
Dr. Scott Van Bramer, Widener University, Chester, PA 19013
This page contains a collection of handouts, spreadsheets, programs, and Mathcad documents
I have developed for teaching Instrumental Analysis (CHEM 366), and Advanced Spectroscopy (CHEM 465) at Widener University. For more resources see the course web pages. Many of the files here require helper applications, additional information is available.
- Basics of Scientific Writing.
An essay about plagiarism and the importance of references in scientific writing. Written in response to student's copying information from textbooks and working together (and claiming to have worked alone).
An HTML document on common statistical tests used for analytical chemistry. Written as an easy to use guide. Includes descriptive statistics, comparison tests, error analysis, linear regression, S/N, and problem sets,
An introduction to Infrared Spectroscopy and greenhouse gases. A set of different greenhouse gases is selected to demonstrate how IR spectroscopy relates to molecular vibration. Includes spectra for HCl, CO2, and CH4 with animations of vibrational modes. Also a Mathcad document that demonstrates the instrumental parameters importat for FT-IR.
Mass Spectrometry Data (EI and CI) from Advanced Spectroscopy, A set of unknown mass spectra for interpretation, Links to other mass spectrometry resources, and a chapter on mass spectrometry.
NMR software used for teaching, Mathcad documents to model NMR data acquisition, NMR data from Advanced Spectroscopy, NMR spectra of unknowns, and links to NMR on the Web.
The Fourier Transform with Mathcad
Mathcad documents showing how the Fourier Transform is implemented and how it extracts frequency
information from a time domain signal.
- Introduction to the Fourier Transform.
- Fourier Transform with two signal frequencies.
- Fourier Transform with Real and Imaginary spectra.
- Fourier Transform with decaying signal.
- Lecture Version, does not contain explanatory text.
