What is molecular physics?
As the name suggests, molecular physics refers to the study of molecules. One of the building blocks of the universe, molecules are two or more atoms held together by attractive forces known as chemical bonds.
Molecular physicists design and conduct experiments to learn more about the structure and properties of molecules. For example, they might study the shape and size of different molecules, or their electric and magnetic properties. This research could also include how these properties change over time or under different conditions.
Molecular physics has numerous real-world applications. Given how minute molecules are, the research methods and techniques used to study them are very precise. Thus, research conducted by molecular physicists has been crucial to the development of precise measurement techniques. Molecular physics is also used in molecular imaging, which is used to visualise cellular processes taking place inside the human body. This visualisation is key for early diagnosis and precise treatment of disease.
What are the typical responsibilities of a molecular physicist?
- Writing hypotheses and theories that explain the properties of molecules, or predict how they’ll react under different circumstances.
- Designing experiments based on these hypothesis.
- Conducting experiments using scientific procedures. X-ray scattering is one technique molecular physicists use to learn more about the structure and properties of molecules.
- Utilising mathematical models and computer simulations to analyse and interpret data from experiments.
- Explaining research findings through writing papers for journals and presenting at conferences.
What skills does this role require?
Attention to detail is crucial. Given that molecules are invisible to the naked eye, you’ll need to be precise and methodical in your research.
An understanding of maths is also important, so you can try out different calculations and mathematical models to design and analyse your research.
Finally, strong communication skills will help you write compelling research papers and grant proposals. Given the real-world application of molecular physics, this will also help you explain your findings to non-specialist audiences.
How do I become a molecular physicist?
One way to enter the field is through university. You could complete an undergraduate degree in a related field, such as physics, maths or a physics specialty. A few universities offer dedicated Chemistry and Molecular Physics courses. Many molecular physicists choose to complete a master’s or a PhD for further specialisation. If you’re not sure that postgraduate study is right for you, the Level 7 Research Scientist Degree Apprenticeship (equivalent to a master’s) provides hands-on training and experience in the field.
