Strong light-matter coupling with quantized electromagnetic fields is at the forefront of experimental and theoretical chemical physics research. Felipe Herrera has recently published a tutorial-style Perspective article in The Journal of Chemical Physics to introduce the field of "Molecular Polaritons" to the broader physics and chemical research community.

The article is written in collaboration with Jeffrey Owrutsky from the US Naval Research Laboratory, and overviews recent experimental and theoretical developments on strong and ultrastrong coupling with electronic and vibrational transitions, with a special focus on cavity-modified chemistry and infrared spectroscopy under vibrational strong coupling. Several opportunities are suggested for further studies that may lead to novel applications in chemical and electromagnetic sensing, energy conversion, optoelectronics, quantum control, and quantum technology.
