The field of cold molecule research has been rapidly developing in the last decade due to the diverse applications of cold and ultracold molecules from fundamental physics to applied chemistry. For example, cold collisions and reactions below 50 K are supposed to play an important role in chemistry in interstellar space. In addition, novel phenomena may arise from the interaction between molecules below 1 K, where the thermal de Broglie wavelength becomes large compared to the classical size of molecules. Furthermore, it has been demonstrated that cold molecules are potential probes of the fundamental symmetry of the universe such as the CPT-violation (Charge, Parity and Time) and the baryon asymmetry. The application of cold molecules to these fundamental physics will be one of the important area of research in physical chemistry in the next decade.

由于冷分子和超冷分子从基础物理到应用化学的广泛应用，近十年来冷分子研究领域得到了迅速发展。例如，低于50 K的冷碰撞和反应被认为在星际空间的化学中发挥重要作用。此外，低于1 K的分子之间的相互作用可能会产生新的现象，其中热德布罗意布罗意波长变得比分子的经典尺寸大。此外，冷分子是宇宙基本对称性的潜在探针，如CPT破坏（电荷，宇称和时间）和重子不对称性。冷分子在这些基础物理中的应用将是未来十年物理化学研究的重要领域之一。
