Drexel University: Chemistry 767: Assignments
Assignment #1, January 10, 1996
The part to be handed in is due Wednesday, Jan. 17 in class.
- Read the Preface and Chapter 1 of Chemical Information Sources, by Gary
Wiggins, McGraw-Hill, 1991. Be prepared for an in-class quiz on this chapter.
- Create your own “research articles” file using the database software
Filemaker on the Macintosh or the equivalent. You may use the Macintosh computers in
Disque 404, or any others at your disposal which have the Filemaker software. For
those not having access to a Macintosh, find the most accessible PC at your work place,
find out what “flatfile” database software, if any, is resident on the
machine, and learn to use it. Hand in a print-out of a typical record in your articles
database file. Indicate what record structure you have settled on for your file.
- Send me an email message (my Internet address is asmith@coasmail.drexel.edu). From here
on, all communication regarding assignments, changes in schedule, or consulting on
specific problems, will be handled through this electronic mail system.
Assignment #2, January 31, 1996
- Names, Registry Numbers, Formulas, and Ring Data from CHEMSEARCH
Last week you were given the names of two chemical substances which appear in the
CHEMNAME file, Dialog database 398. In this assignment, you will use both CHEMNAME
and print handbooks, catalogs, or dictionaries, to find out what you can about these
substances. Your final report should include the answers to the following questions
for each of the two names you were given:
How many records in CHEMNAME correspond to the chemical name? If there is more
than one record for a given name, examine some of the multiple records to see why
there are so many, and try to find what you consider to be the most fundamental
record (i.e., that for a single chemical substance with that name). Once you have
found this record, save it and print it out in FORMAT 4 (full record with tagged
fields). Indicate on the print-out the molecular formula, the CAS registry number,
and the ring data. From the data provided, see if you can draw the 2-d structure of
the compound (it may not be possible). Find and photocopy entries from handbooks,
catalogs, or dictionaries that also describe this compound.
- Using the CHEMNAME file on DIALOG
Answer the following questions:
- How many chemical substances are derived from palm oil?
- What is the chemical substance name for Prussian Blue?
- How many known isomers are there of C10H8?
- Formulate a search question of interest to you regarding some chemical substance. Use
the CHEMNAME file on DIALOG to refine or expand the search question so that you
retrieve at most three records corresponding to the substance. Save them and print
them out in FORMAT 4.
- Using NETSCAPE
Use the Netscape Web Browser to download from DIALOG’s home page the blue sheets
for the following three databases: CA Search, CHEMNAME, and Beilstein. Print them out
and bring them to all subsequent classes.
In-class Assignment, August 23, 1995
On Tuesday at the American Chemical Society’s national meeting in Chicago I heard an
excellent talk by J. Gasteiger. Using the SciSearch database on DIALOG, answer the following
quesions:
- What is Gasteiger’s present affiliation?
- For how many records in SciSearch is Gasteiger one of the authors?
- What is the earliest publication referenced in SciSearch by Gasteiger?
authors:
title:
journal name:
volume:

- Find a paper by Gasteiger that is cited by more than 300 subsequent papers.
authors:

From the fields in the SciSearch record, describe the research area in which Gasteiger
publishes.
- In his talk, Gasteiger mentioned a review article he published in 1993 in Chemical
Reviews. Find this article.

From the fields in this SciSearch record, describe the research area in which Gasteiger
wrote this review.
- There is a subsequent paper by Gasteiger in 1994 in the Journal of Chemical Information
and Computer Sciences on a closely related topic. From the abstract of this article,
describe the work.
- Make an alphabetical list of the ten most common journals in which Gasteiger has published
in the past fifteen years.
