"Laboratory work on molecular physics: a textbook for students of the specialties "Physics" and "Physics of condensing states" is an indispensable resource for students and teachers seeking to understand more deeply the intricacies of molecular physics. This manual, created by a team of authors, contains practical tasks that will help not only to consolidate theoretical knowledge, but also to develop the skills of experimental thinking. The book is a systematic set of laboratory papers covering a wide range of topics related to molecular physics. Each work is carefully designed taking into account the current problems and technologies used in modern physics. The reader will be able to immerse himself in the study of such key concepts as thermodynamics, kinetic theory, the properties of gases, liquids and solids, as well as the interactions between molecules. These topics are not only relevant for physics students, but can also be of interest to those who are fond of chemistry, materials science and engineering sciences. This manual will be especially useful for senior students, graduate students and teachers who are looking for high-quality and affordable materials for laboratory classes. It will be an excellent help for those who want to deepen their knowledge in the field of molecular physics and learn how to apply theoretical concepts in practice. In addition, the book may be of interest to researchers working in related fields, such as condensed matter physics and nanotechnology. One of the main topics raised in this manual is the importance of the experimental approach in the study of physical phenomena. The authors emphasize that without practical experience it is impossible to fully understand the complex concepts of molecular physics. Each laboratory work is accompanied by detailed instructions that will help students not only to conduct an experiment, but also to analyze the results, which is a key point in scientific activity. The style of the authors is distinguished by clarity and accessibility of presentation, which makes the material understandable even for those who are just beginning their acquaintance with molecular physics. They use simple and illustrative examples to help readers better internalize complex theoretical aspects. The team of authors includes experienced teachers and researchers, which guarantees high quality of the presented material. If you are looking for additional books on molecular physics, you should pay attention to such works as "Molecular Physics" and E. Tikhonov and Condensed Matter Physics A. L. Iofe . These books can also be useful for in-depth study of the topic and broadening your horizons. "Laboratory work on molecular physics" is not just a manual, but a whole world that opens doors to an exciting and complex world of molecules and their interactions. It will help students not only gain the necessary knowledge, but also develop critical thinking, which is an important skill in any scientific field. If you want to become a true expert in molecular physics, this manual will be your reliable companion along the way.
