SECOND ANNOUNCEMENT

A meeting organised by the UK Astrophysical Chemistry Group

a special interest group of

the Royal Society of Chemistry and the Royal Astronomical Society


POLYATOMICS AND DIBs IN DIFFUSE INTERSTELLAR CLOUDS


will be held in rooms E6 and E7, Renold Building, UMIST, Manchester M60
1QD on Wednesday 8th (from 10.30 am) and Thursday 9th January 2003

MEETING WEBSITE is accessible from the UMIST Astrophysics Group webpages
http://saturn.phy.umist.ac.uk:8000/

AIM OF THE MEETING
During the last decade, the chemical complexity of interstellar
diffuse clouds has been demonstrated to be much greater than previous
recognised. A variety of polyatomic molecules is now known to exist in
regions previously believed to contain only atomic and diatomic
species. Over the same period, the unidentified diffuse interstellar
bands (DIBs) have been intensively studied, and there is now a general
consensus that many of these features are carried by molecules rather
than dust. The aim of the meeting is to bring together these two
topics that are often discussed separately, to address the questions
such as:

What are the polyatomics that have been discovered in diffuse
interstellar clouds? Do we understand how they are formed? Do these
formation mechanisms also imply the existence of large polyatomics?
What is the evidence for large molecules being the DIB carriers? What
is the origin of such large molecules in the diffuse clouds?


PROGRAMME
There will be four invited reviews, each one hour long including
discussion, and contributed talks, each of 20 minutes including
discussion. The oral presentations will be in room E7.

There will also be poster presentations in room E6.
