6. MORE TARTRATES: THE PHYSICIST’S PLAYGROUND Cotton’s discovery of circular dichroism raised so much interest in Brace’s Physics Laboratory at the University of Nebraska that it was decided to construct an improved and more sensitive apparatus for measuring both elliptical polarization and rotation, in order to repeat and extend the French findings. The American physicist DeWitt Bristol Brace was himself active in the field of optical activity and had in 1904 described an elliptical polarizer and compensator that was incorporated not only in the optical system used in Nebraska, but also later in Europe.

In Jaeger’s extensive paper of 1919 [51], many such plain curves are reported, but only two cases of a bona fide Cotton effect, namely, in K3 [Cr(ox)3 ] (Cotton effect near 565 nm) and K3 [Co(ox)3 ]·H2 O (near 620 nm). The chromium compound had already been synthesized and resolved by Werner in 1912, but had not been investigated by spectropolarimetry, whereas the (trisoxalato)cobaltate(III) was new. It was very advantageous that Jaeger could induce Israel Lifschitz (1888–1953), Private Docent at the University of Zurich, to join his laboratory in 1921.
