The release contains two components:

LITHIUM Base, the enterprise platform that allows users to
automate repetitive tasks through automatically generated
procedures that can be played back later on the same or other
relevant models and shared with others

LITHIUM Developer, the platform for LITHIUM-based applications
that supports custom interfaces and applications based on
organizations' specific needs

"The philosophy behind LITHIUM is not to transform a research
organization's laboratory scientists into expert computational
scientists, but to deliver modelling results and knowledge to those
researchers who need to use them," said Dr., Tripos spans the
world with global research operations and an international client
base., and/or its affiliates in the United States and certain other
countries.

Desktop Access to Computational Information

Tripos, Inc.

chemists organometallic

Specifically designed to foster communications between front-line
life sciences researchers and expert computational chemists, LITHIUM
allows researchers to view, evaluate and share insights on molecular
data among their colleagues. "The technology is
designed to empower the laboratory chemist and biologist to make
better, faster and more-informed decisions regarding which compounds
to explore and synthesize by providing access to 3-D chemical
information."
