On behalf of the Organizing Committee, it is indeed a great honor and pleasure to invite you all to the Twelfth International Symposium on Two-dimensional Correlation Spectroscopy (2DCOS-XII), which will be held on August 17-18, 2023.

The International Symposium on Two-dimensional Correlation Spectroscopy (2DCOS) is a sequential symposium worldwide.
Since the first symposium, which was held in Sanda, Japan in 1999, 2DCOS has become an important international forum in the community of two-dimensional correlation spectroscopy (2D-COS).
The symposium covers all aspects of 2D-COS ranging from basic theory to applications in various scientific fields including chemistry, physics, material sciences, life sciences, and nanosiences. Not only vibrational spectroscopy, but also any other topics concerning 2D-COS may be included.

Following the great success of the previous eleven symposia, the virtual 2DCOS-XII in Kangwon Radiation Convergence Research Center, Kangwon National University, Chuncheon, Korea will be run by using basically only cloud contributions of prerecorded presentations.

Your active participation in the 2DCOS-XII will certainly make a successful conference. Please make your calendar-the 2DCOS-XII on August 17-18, 2023.

In addition, 2DCOS-XII is very happy to announce that Prof. Kazarian and Prof. Blades of Applied Spectroscopy have arranged a special issue to accommodate the selected manuscripts of 2DCOS-XII. (Prof. Young Mee Jung and Prof. Yizhuang Xu have been assigned as guest editors of the special issue).

We look forward to seeing you in 2DCOS-XII.

Young Mee Jung
Chair of 2DCOS-XII
