1. Introduction 

1.1  What is ACD/I Lab 

ACD/I Lab is the Internet based service that allows you to get instant access to ACD/Labs 

chemical databases and property predictions programs via the Internet. 

1.1.1 ACD/Public I Lab 

Public access to the latest versions of I Lab services is available from the ACD/Labs website.  

Public I Lab includes both fee based and free services (the number of available services 

depends on your login type: authenticated user, guest, or sight license).  I Lab registration and 

membership are free.  An account on the Interactive Lab can be set up from 

http://www.acdlabs.com/ilab

 or via ChemSketch.  As of Spring 2004, a 2 week demo period 

can be arranged for I Lab.  Users with ChemSketch 6.0 and later can access I Lab automatically 

if run on a PC with Internet connection. 

Note 

Some of the I Lab options are available for ACD/I Lab: Intranet Edition only.  In this 

guide, these are marked as 

 For I Lab: Intranet Edition only! 

1.1.2  ACD/I Lab: Intranet Edition  

I Lab can also be packaged for use in your Corporate Intranet environment.  Using I Lab behind 

a corporate firewall allows you to use the corporate security infrastructure to keep I Lab 

transactions secure.  In addition to a standard set of I Lab services, I Lab: Intranet Edition allows 

you to improve prediction results by training predictors with your own experimental data (for more 

information, refer to Section 3.6.1). 

Note 

Some of the I Lab options are available for ACD/Public I Lab only.  In this guide, 

these are marked as 

 For Public I Lab only! 

1.2  What's New in 8.0 

1.2.1  HNMR DB  

The expanded DAT file now contains over 1,384,000 experimental chemical shifts and 449,000 

coupling constants for over 165,000 structures. 

The internal ACD/Labs database contains very recent entries.  Over 3300 entries are from 

articles published in the year 2001.
