Preface to Special Issue of \the 3rd Asian Workshop on Molecular
Spectroscopy" and \the International Workshop on Astrochemistry
Relative to some newly emerging elds, molecular
spectroscopy is already an ancient discipline with a his-
tory of nearly 100 years. On the one hand, molecular
spectroscopy techniques and methods have been used in
various elds, from analyzing the components of breath-
ing gases to diagnose diseases, to listening to spectacu-
lar narratives from the depths of the universe. On the
other hand, advancements in modern laser technology
and computational analysis methods never stop push-
ing molecular spectroscopy to absorb new elements and
reach unprecedented heights. Communication among
molecular spectroscopists has brought the frontiers of
this discipline to a deeper and broader eld. In recent
years, the voices of spectroscopists from Asia are getting
louder and more impressive in the world. To attract
more young researchers to this eld, a group of my col-
leagues has launched the Asian Workshop on Molecular
Spectroscopy (AWMS).
Building on the great success of the 1st and 2nd
AWMS held in Kyoto (2017) and Taoyuan (Taipei,
2018), we held the 3rd AWMS in Hefei on March 7 to
9, 2019. Over 120 researchers from many countries at-
tended the meeting and presented over 40 talks and 30
posters. Most of them were given by young faculties and
graduate students, following well with the spirit of the
meeting. Here, we invite some attendees to publish their
excellent works in this special issue of Chinese Journal
of Chemical Physics.
Unfortunately, two members of the Committee initi-
ated AWMS, Li-Hong Xu and Jon Hougen, who made
irreplaceable contributions, left us just two months be-
fore the 3rd AWMS meeting held in Hefei. This meeting,
together with this special issue, allowed us to remember
them again and thank them for their outstanding con-
tribution to our community.

The development of science and the advancement
of technology have enabled human beings to expand
our understanding of the universe. In the interstellar
medium, more than two hundred molecules, including
complex organic ones, have been detected. Astrochem-
istry, the in-depth study of these interstellar molecules,
has made great progress in recent years and has become
an important frontier of international scienti c research.
Teams from all over the world have conducted research
on molecular observations, chemical mechanisms and
physical environments in molecular clouds, star forming
regions, protoplanetary disks, di use clouds, transpar-
ent clouds, photo dominated regions, and circumstellar
regions, and have achieved fruitful results. Especially in
China, the number of teams engaged in astrochemistry
has been increasing, new results have emerged, and more
teams have shown strong interests in Astrochemistry.
As an interdisciplinary eld, the development of As-
trochemistry is dependent on the close cooperation of as-
tronomers, physicists, and chemists, in the aspects of ob-
servation, theory and experiment. Xinjiang Astronom-
ical Observatory CAS, with the co-organizer National
Time Service Center CAS, hosted the \Astrochemistry
(2019) International Workshop" in Xi'an, China from
May 17th to May 20th, 2019. Over one hundred experts,
scholars, and students from universities, research insti-
tutions, and scienti c companies attended the workshop.
The attendees reported on scienti c progress, exchanged
collaborative needs, and discussed the frontier of Astro-
chemistry research. Thirty oral and twenty seven poster
presentations were given at the workshop. Here we select
eight studies in excellency to publish on Chinese Journal
of Chemical Physics.
Based on the present, looking forward to the future,
we all work together to promote the further development
of the eld of Astrochemistry research.
