Rowland's research, first published in Nature magazine in , initiated a scientific investigation of the problem. The Physical Sciences Building at the University of California, Irvine, which held his laboratories for many years, was renamed Rowland Hall in his honor that same year.

Rowland moved to Irvin to become Professor of Chemistry and also the first Chairman of the Chemistry Department of the yet-to-be-opened the University of California, in August In spite of the transfer, he continued receiving support from AEC. Students began to arrive by September At the same time, Rowland deliberately sought new topics, trying to instill some freshness in the research work.

Thus they first worked on radioactive tracer photochemistry, using tritium and carbon; then chlorine and fluorine chemistry using the radioactive isotopes 38Cl and 18F. Rowland began working with Mario J. Molina, at Irvine in the early s. Rowland theorized that man-made organic compound gases combine with solar radiation and decompose in the stratosphere, releasing atoms of chlorine and chlorine monoxide that are individually able to destroy large numbers of ozone molecules.

Further validation of their work came in the mids with the discovery of the so-called hole in the ozone shield over Antarctica. In an international protocol to ban the production of ozone-depleting gases was negotiated by the United Nations in Montreal. Rowland traveled to Salzburg, Austria to attend an International Atomic Energy Agency meeting on the environmental applications of radioactivity and had much close interactions with specialists in the field, in In January , he attended another such meeting held in Fort Lauderdale, Florida.

It was here that Rowland first learned about the traces of chlorofluorocarbon a man-made chemical found in the atmosphere both at the northern and southern hemisphere. Rowland is best known for his extensive research in radiochemistry. He was the one who discovered chlorofluorocarbons contributing to ozone depletion. He announced after his discovery that industrially developed gases influenced by solar radiation were decomposing in the stratosphere.

This action then released vast amounts of chlorine, chlorine monoxide in the stratosphere. The release of chlorine and its monoxide in quantities that destroy ozone. That year a ban was issued towards the CFC-based aerosols in spray cans. This ban was firstly carried out in the US. It was not until when a global ban was issued. Rowland performed many measurements of the atmosphere.

The World War II ended in the same year while he was still a trainee. However, he had to wait for fourteen months before he was released from the Navy. Concurrently, he spent the summers of , and working at the Chemistry Department of the Brookhaven National Laboratory. While working at Brookhaven, he put powdered mixture of the sugar glucose and lithium carbonate into the neutron flux of the nuclear reactor.

It resulted in one-step synthesis of radioactive tritium-labeled glucose. However, before anything could materialize, he received appointment as an Assistant Professor at the University of Kansas and joined his new post in the summer of The support promised by AEC also arrived on time. He therefore, lost no time in gathering a research team, comprising of graduate student and postdoctoral fellows.

For next eight years, he worked with this research group, investigating mainly the chemical reactions of energetic tritium atoms.
