PhD position at VU University Amsterdam
Job Level: Other
Job Type: Academic
Expire Date: 2017-06-23
Photoabsorption and dissociation of CH and carbon-based radicals
At LaserLaB VU University Amsterdam we have an opening for a PhD student working on the spectroscopy of carbon-based molecules in connection to the chemistry of the interstellar medium. Several techniques will be employed for the spectroscopy: cavity ring-down laser spectroscopy, laser-induced fluorescence, multi-photon ionization. Carbon-based radicals will be produced in plasma jet expansions. The project is connected to the long-standing problem of the Diffuse Interstellar Bands. Part of the experiments will be performed at the Soleil synchrotron in Paris using the unique Fourier transform vacuum ultraviolet spectrometer fed with VUV from the synchrotron.
The work is part of a larger consortium of the Dutch Astrochemistry Network with several groups (including 12 young scientists) working in collaboration.
Students of all nationalities, with Masters Degree in physics, chemistry, astronomy or engineering are eligible. Knowledge about molecular spectroscopy is a considered an advantage.
The PhD position is funded (by the NWO Dutch Astrochemistry Network) with full salary for 4 years. Salary, growing from 2,191 € gross per month in the 1st year to 2,801 € is supplemented with a holiday allowance of 8% and an end-of-year bonus of 8,33%. Employment is by Vrije Universiteit Amsterdam.
Contact for application and more details: Prof. Wim Ubachs (email@example.com).

Postdoctoral position in the HITRAN group
Job Level: PostDoc/Short-Term
Job Type: Other
Expire Date: 2017-06-16
The HITRAN group (www.hitran.org , Atomic and Molecular Physics Division,
Harvard-Smithsonian Center for Astrophysics, Cambridge, MA, USA) is looking for
Postdoctoral associate. Postdoc will be involved in work on the HITRAN and
HITEMP compilations. The responsibilities will include construction of the
spectral line lists for the molecular species relevant to the modeling of
planetary atmospheres. This will include, but is not limited to, collecting
available experimental and theoretical data, assessing their quality and
creating semi-empirical models for calculating parameters that are not
available in the literature. In addition to being co-authors on the widely cited
HITRAN and HITEMP papers, the candidates will have an opportunity to work on
first-author publications in the field of atmospheric and/or astronomical
spectroscopy. Some examples of the publications are given below this ad.
The candidates are expected to have a working experience in the field of molecular spectroscopy (understanding of different types of molecular symmetries, transitions, selection rules, working with Hamiltonians, etc). Experience with FORTRAN and/or Python is required. Proficiency in the English language and good communication skills are required. Candidates will have to be able to work both independently and within a team. Applicants are expected to have completed their PhDs no earlier than July 2011 and be able to start their duties no later than September 1, 2017. In addition, the candidates should have experience in at least three out of the five areas listed below
1. First hand experience with the HITRAN and/or HITEMP databases.
2. Working knowledge of line-shape parametrizations (including the Hartman-Tran profile) and their implementations. Experience with line mixing is a plus.
3. Experience with commonly used spectroscopic programs for fitting and predicting spectra. For instance, LEVEL, SPFIT, PGOPHER, etc
4. Experience in Structured Query Language (SQL). In addition, experience with Django and Apache is a big plus.
5. Proficiency in writing scientific papers, manuals and other types of documentation.
The position is for one year and provides a stipend of about $60,000 per annum. Depending on the performance and the availability of funding, the position may be extended to another year. Medical insurance can be covered.
Applications (with CVs) should be sent to Dr. Iouli E. Gordon (firstname.lastname@example.org). Three reference letters should be sent independently by scientists providing recommendations.
