How did Elmer Imes contribute to the atomic theory?
The work presented the first accurate measurement of the distance between atoms in molecules. Imes’ work showed that quantum theory could be applied to the rotational energy states of molecules as well as the vibrational and electronic energy levels. In 1919, about a year after completing his Ph.
What is Elmer Imes known for?
Elmer Samuel Imes (October 12, 1883 – September 11, 1941) was the second African American to earn a Ph. D. in physics and the first in the 20th century. He was among the first African-American scientists to make important contributions to modern physics.
What did Elmer Imes invent?
Imes used his instruments to measure absorption bands in the near-IR region for three hydrogen halides: HCl, HBr, and HF. Imes’s final spectrometer, used for his most precise work, actually consisted of two devices working in tandem. The first was a prism spectrometer, and the second was a grating spectrometer.

What did Elmer Imes do for a living?
He was among the first African-American scientists to make important contributions to modern physics. While working in industry, he gained four patents for instruments to be used for measuring magnetic and electric properties. As an academic, he developed and chaired the department of physics at Fisk University, serving from 1930 to 1941.
When did Elmer Imes graduate from Fisk University?
Imes returned to Fisk in 1913 as an instructor of science and mathematics. During his tenure there, Imes also earned a master’s degree in science from Fisk University. He went to the University of Michigan for additional study in physics, earning a Ph.D. in physics in 1918. He studied under Harrison McAllister Randall.
Where did Benjamin and Elizabeth Imes come from?
Benjamin was descended from free people of color, who had been established in south-central Pennsylvania by the time of the Revolution. His mother Elizabeth was born into slavery; her family had moved to Oberlin when she was a child, after the American Civil War and emancipation.
