  1. Eric Herbst The Ohio State University SOME ASPECTS OF GISBERT’S CAREER

  2. Curriculum Vitae • 1936 Birth (Karlsruhe, Germany) • 1967 Ph. D. (Duke Univ., spectrum of HSSH) • 1967-68 Postdoc, Duke Univ. • 1968-70 Postdoc, NRC (with Costain/Oka) • 1970-71 Asst. Prof., Univ. Brit. Columbia • 1971-72 Visiting Scientist, NRC • 1972-79 Astronomer, MPIfR • 1979- Chair in Physics, Univ. of Koeln • Honors: Max-Planck Research Prize; Phillip • Morris Prize; Marci-Medal; Historic Medal • of Charles University

  3. I. Physikalisches Institut, Koeln • Size: 100 people (students, researchers, machinists, etc.) • PhD’s granted: 100 • Yearly funds: 8 000 000 euros • Construction of astronomical hardware for a variety of telescopes in-house (KOSMA, SWAS, HIFI, SOFIA)

  4. ASTRONOMY 1) New species & isotopes 2) Maps & physical conditions (e.g. CI & CO) 3) Cologne telescope 4) Development (e.g. AOS’s) SPECTROSCOPY 1) mm/submm studies including intracavity work 2) THz studies 3) IR studies 4) Database SOME CAREER HIGHLIGHTS

  5. SOME SPECTROSCOPIC EQUIPMENT • THz spectrometers (BWO sources up to 3 THz, sideband source 1.6-2.1 THz; used for study of rotation, torsion, bending vibrations of radicals and normal species) • OROTRON intracavity mm-wave spectrometer; up to 400 GHz; 3 orders of magnitude enhancement in sensitivity (van der Waals species, etc) ---------------------------------------------------- frequency-stabilized ring laser for IR work

  6. The Russian Connection • BWO’s supplied by ISTOK Research and Production Company (Fryazino, Moscow Region) • Tunable millimeter-wave synthesizers supplied by Institute of Electronic Measurement, KVARZ, Nizhnii Novgorod • Orotron – Russian Academy of Sciences

  7. HSSH AND BRETHREN HSSH HSOH HOOH

  8. And another look….. The middle species, HSOH, took many years to learn how to produce! Winnewisser et al. (2003)

  9. HSSH (disulfane) c-type transitions G. Winnewisser, PhD thesis (1967)

  10. Some Unusual Aspects of HSSH • Nearly perfect accidental symmetric top • Ortho-para structure • Internal rotation over 4p radians

  11. Rotational-Torsional Levels -1 -1 2843 cm 2037 cm

  12. Note: ortho-para intensity variation!

  13. HSOH rQ0-BRANCH (2003) Winnewisser et al. (2003)

  14. trans-Ethyl Methyl Ether U. Fuchs et al. (2003)

  15. Rotational Spectra of Radicals Some examples of recent years: CH2NH NH2 PH PS CP CF CN Plus the ion HCS+ through 1 THz

  16. interstellar

  17. CH2 Michael et al. (2003)

  18. Low Frequency Bending of C3 Sideband spectrometer Also infrared studies – see G. Fuchs (2003)

  19. KAO Confirmed by ISO Giesen et al. (2001)

  20. HNC **(lab;1976) Vinyl cyanide (1975; Sgr B2) Formic acid HCOOH (1975; Sgr B2) CH3CCCCH (1984: TMC-1) NH2D (1985; 3 clouds) Three 13C isotopomers of HCCCN (1975,1977; Sgr B2,fractionation), NEW INTERSTELLAR MOLECULES

  21. TMC-1 In 1978, Churchwell, Winnewisser, and Walmsley put TMC-1 on the map (despite thunderstorm; pointing errors) “Molecular Observations of a Possible Proto-Solar Nebula in a Dark Cloud in Taurus” In the following, we will refer to this small cloud as the Taurus Molecular Cloud 1, or TMC1…….

  24. HISTORY OF KOSMA • 1984 KOSMA 3-m first light • 1985 move to Gornergrat • 1995 new dish and mount

  25. SELECTED KOSMA CO and CI STUDIES • 2003: Virgo cluster spiral galaxies • 2002: CI emission from star-forming regions (1-0 & 2-1) • 2000: Cepheus B cloud • 2000: high latitude cloud MBM 32 • 2000: galactic 5kpc ring • 1998: Rosette molecular complex • 1998: Comet Hyakutake • 1991: fragmentation in California nebulae • 1991: L1495 survey • 1990: nearest cloud (L1457): fragmentation

  26. Latest CO and C I Studies(The New Generation) • New array receiver: 2 X 4 pixel 490/810 GHz (SMART) (Graf et al.) • C I: ability to study 1-0 (492 GHz) and 2-1 (809 GHz) fine-structure lines simultaneously • CO J=7-6

  27. Non-Kosma C I studies • Heinrich-Hertz telescope: 1997 • Study of starburst galaxy M82 using 1-0 and 2-1 simultaneously • Antarctic Submillimeter Telescope & Remote Observatory: 1997 • Study of cold, low density clouds towards the galactic center broad-line emission

  28. Some Recent Observations • Excited HCN in the protoplanetary nebula CRL 618 (2003) with MPIfR (Bonn); deduction of physical conditions • Unusual isomers of CO in Rho Ophiuchi (e.g. 13C17O) based on precise laboratory data (2001-2003) • SWAS

  29. PRESENT & FUTURE WORK • SPECTROSCOPY • IR studies of carbon clusters (C8) • Mm-wave studies of van der Waals species • Free radicals at THz frequencies (CH2) • Molecular ions • ASTRONOMY • SOFIA & HERSCHEL (HIFI) • Database for THz astronomy (CDMS)

  30. DEAR GISBERT, Best wishes for the future, and thank you for all of the happy and exciting times we have spent and will continue to spend together.
