  2. Part 1 Introduction, Instruction, Teaching Schedule, Course Requirements, and Objectives

  3. Instruction Instructors: Prof. Ben Zhong Tang (BZT) Rm. 4532; Tel. x7375; tangbenz@ust.hk Mr. Steve Yip, Librarian (SY) Tel. x6756; lbsteve@ust.hk TA: Mr. Jianzhao Liu Rm. 7140; Tel. x7396; liujz@ust.hk Class Times Mondays, 16:00-16:50 (4:00-4:50 PM) and Venue: Rms. 4621 & 4402 (Computer Barn A) Prerequisite of Chem392 Students with PASS grade will proceed to Chem392

  4. Prerequisites, Textbook, and Accessories Prerequisites: Basic knowledge of nomenclature of chemical compounds Basic knowledge of library facilities is assumed Requirements: Attendance at Lectures Participation in class exercise Pass in literature search assignment Grading: Pass/Fail based on - attendance (2-times absence of class: fail) - search assignment (Report not sent in on time: fail)

  5. Teaching Schedule(Total: 6 weeks) Introduction 1st week (Jan 29) BZT/4621 Library resources 2nd & 3rd weeks (Feb. 5 & 12) SY/4621 Primary/secondary literature 4th week (Feb 26) BZT/4621 Search demonstration 5th week (March 5) BZT/4402 Search practice 6th week (March 12) BZT/4402

  6. Prerequisites, Textbook, and Accessories • R. E. Maizell “How to Find Chemical Information” 3rd Ed. Wiley, New York 1998: QD 8.5 M34 1998 • “Information Sources in Chemistry” 4th Ed. ed. R. T. Bottle and J. F. B. Rowland, Bowker-Saur, London, 1993: QD 8.5 147 1993 • G. Wiggins “Chemical Information Sources in Chemistry” 4th Ed. ed. R. T. Bottle, McGraw Hill, New York, 1991: QD 8.5 M54 1991

  7. According to Oxford English Dictionary • Information: • Communication of the knowledge of some fact or occurrence • Knowledge of facts • Communication about a particular subject • Knowledge: • The fact of knowing a thing, state, person, etc. • Understanding of a branch of learning • Theoretical or practical understanding of something • Apply to the science of chemistry: • An understanding of what things are • How they interact and may be manipulated and changed • Structure …

  8. Course Objectives Why Chemical Information – acquisition of ChemicalKnowledge? CHEM 398/PG (M.Phil. or Ph.D.) research, research articles, etc. . Structure of a compound for which you have the trivial name* (see example) . Trivial or systematic name for the compound for which you have the structure . Physical properties of a compound . Biological or medicinal properties of a compound . Whether there are similar compounds described in the chemical literature . Method of preparation(s) of a compound . Whether a proposed structure is chemically realistic (see example) . An aspect of calculation of a proposed structure, transition state, reaction, etc . Spectroscopic properties of a compound . And so on …… * A common, historic, or convenient name for a substance, derived often from the source in which the substance was discovered, but unsystematic and not used in modern official nomenclature, as sucrose for -D-fructofuranosyl--D-glucopyranoside.

  9. Examples • What is “Teflon”? • Can you make a compound with the following structure?

  10. Course Objectives (cont.) For conduct of any research project or exercise, acquisition of relevant information - knowledge of the topic - is absolutely essential • Knowledge …. assists in the design of the project and development of new experiments • Knowledge …. is the basis of insight and explanation • Knowledge …. assists creativity, makes you more aware • Knowledge …. prevents duplication of previous work … surprisingly frequent! • Knowledge …. saves an enormous amount of time • Knowledge .… impresses your supervisor or employer • Knowledge .… makes you independent

  11. Course Objectives (cont.) The objective of the course is to instruct you to access relevant chemical information efficiently, quickly, thoroughly … Not easy ……! • Probably over 30 million discrete chemical substances known - elements, chemical compounds, polymers, materials, etc. • Enormous mountain of physical and chemical property data • - thermodynamic properties (H, G, S ……) • - kinetic properties (Ea, k, …..) • - structural data (bond lengths, angles, symmetry, shape …) • - spectroscopic properties (NMR, MS, IR, Raman, UV-VIS …) • - electrical, magnetic, and optical properties • Enormous number of chemical reactions, synthetic methods, • purification methods, etc.

  12. Course Objectives (cont.) • Not easy (cont.) ……! • Relevant information may be buried in ……. • - one of over 100,000 scientific journals … • - one of several million patents …. • - a conference paper • - a dissertation (M.Phil./Ph.D. thesis or equivalent) • - compendia of data or properties • - a review or technical report • - in an abstract of the original article in Chemical • Abstracts or similar abstracting service • Relevant information may be in English, Chinese, • Japanese, German, French, Italian, Spanish, Russian, … • Source may be ‘hard copy’ or ‘electronic’ Where do we start?
