Dr. W. Stephen McNeil is an Associate Professor in the Department of Chemistry at UBC Okanagan, in Kelowna, British Columbia. Information regarding Dr. McNeil's research interests and publications may be found on his faculty research page.
Dr. McNeil often teaches courses such as Chem 220 (Atomic Structure and Molecular Bonding), Chem 335 (Bioinorganic Chemistry), and he occasionally forays into general, main group, and organometallic chemistries.

If you're a chemistry or biochemistry student, you need a program to draw proper chemical structures.
• MarvinSketch is Java-based, and will run on PC, Mac, or Linux.
• Both ACDLab's Chemsketch and Accelrys' Accelrys Draw are PC programs that are free for academic and personal use.
Need a periodic table? Of course you do. Your choice:
• A practical table with element names and molar masses, in either black and white or colour.
• Another attractive colour table, from ptable.com.
• Or, if none of those strikes your fancy, try one of these.
Looking for reference data for that lab write-up? Try these sites:
• Webelements and PTable have more data on the elements than you could ever hope to use.
• The CRC Handbook of Chemistry and Physics
• The PubChem offers basic physical properties and bioloigcal / pharmacological activity information on small molecules.
• The NIST Chemistry WebBook
• The NIST Computational Chemistry Comparison and Benchmark Database has experimental physical data on over 1500 compounds, such as bond lengths and angles, vibrational frequencies, formation enthalpies, and dipole moments.
• Properties of Organic Compounds (over 29000 of them)
• The Spectral Database for Organic Compounds (SDBS)
• Nakamoto's Infrared and Raman Spectra of Inorganic and Coordination Compounds:
• Part A is theory and main group compounds
• Part B is coordination compounds, organometallics, and bioinorganic.
• Online Material Saftey Data Sheets (MSDS) at the Canadian Centre for OHS
• Sigma-Aldrich can tell you the expected melting point, boiling point, flash point, and IR and NMR spectra of all your reagents and hoped-for products in your organic lab, and, if you screwed up the prep, they'll sell them to you.
• Do you have mysterious extra peaks in your NMR spectrum? You need this Organometallics paper and this J. Org. Chem. paper to figure out what they are. There, aren't those the most useful references ever?
Think those latex gloves protect your hands from the solvents you're handling? Yeah, not so much.
There are many databases of Jmol molecules to look at, including those at:
• ChemTube3D, featuring models of hundreds of inorganic compounds. However, anaylze these structures critically before using them. Many models are based on qualitative idealized structures rather than experimental data (e.g. the bond angle in NF3 is not 109.5°), and many are simply wrong (e.g. [I5]+ isn't a W, Cl2O6 does not have equivalent Cl atoms, TeO4 doesn't exist, [NO2] and N2O4 do not have unequal N-O bond lengths, [Ni(CN)4]2 is not tetrahedral, etc.).
• Purdue University (lots of simple organic and inorganic molecules, coordination complexes, and inorganic crystals)
The Royal Society is dedicated to furthering informed communication between media and the scientific community, and is an excellent source of reliable scientific discussion about matters of current importance. Want to know what scientists really think about genetically-modified foods, global warming, or human cloning, and why?
You need to know How Stuff Works.
Believe it or not, there are sometimes even interesting research articles published in fields other than chemistry.
Dr. McNeil comes to UBC Okanagan by way of the other University of British Columbia, the University of Washington, and Douglas College, whereby he has acquired an inordinate fondness for organometallic reaction mechanisms, well-crafted Americanos, and active-learning teaching strategies. He is a member of the Canadian Society for Chemistry Inorganic Division, the Chemical Institute of Canada Chemistry Education Division, the American Chemical Society, the Society for Teaching and Learning in Higher Education, and Project Steve.
His ongoing interests include the use of new cobalt compounds as mediators for controlled radical polymerization and potential pharmaceutical agents, the development and assessment of innovative chemistry education student-engagement strategies, science communication and chemistry outreach, and esoteric and expensive board games. Ok. What's next?
