Heinz-Detlef Kronfeldt

from Wikipedia, the free encyclopedia

Heinz-Detlef Kronfeldt (born February 6, 1949 in Berlin ; † October 15, 2015 there ) was a German physicist and university professor .

Life

After graduating from high school , Kronfeldt studied physics at the TU Berlin with a diploma in 1975. At the Institute for Optics and Atomic Physics there , he wrote his dissertation laser spectroscopic and interferometric investigations of electrical and magnetic hyperfine interactions on sodium with Roland Winkler, head of the spectroscopy group , Rhenium and Europium , with which he received his doctorate in 1979 . He completed his habilitation in 1989 and, after Roland Winkler's retirement, became head of the working group.

Kronfeldt's main focus was initially on high-resolution laser spectroscopy to investigate the hyperfine structure and the isotope shift of the lanthanides . In 1997 he hosted the 29th annual conference of the European Group for Atomic Spectroscopy (EGAS) . The next focus of work was molecular spectroscopy with analysis of rotational vibration spectra with IR lasers . He developed a mobile system for highly sensitive trace gas analysis in the atmosphere . As part of three EU projects between 1997 and 2013, sensors suitable for the sea were developed with which trace concentrations of contaminants in seawater could be detected using surface-enhanced Raman spectroscopy (SERS) . From 2006 he developed a mobile Raman system for the detection of meat spoilers in meat. His "laser pistol" became very well known in the media due to the rotten meat scandals . His review article Raman Spectroscopy in Food and Seawater Analysis appeared in the Encyclopedia of Analytical Chemistry .

From 1989 until his retirement in 2014, Kronfeldt was in charge of the basic physics internships I – III at the TU Berlin, and together with Hans Joachim Eichler and Jürgen Sahm he published the textbook Das neue Physikalische Grundpraktikum . From 1996 to 2005 he was managing director of the German Physical Society in Berlin .
