New: Summer School becomes International School.
Although September is still considered late summer, we feel it is more appropriate to rename our school International School.
What we used to call Summer School for years is now called International School.
However, the content and focus have not changed, and we continue to offer our participants an interesting and comprehensive program covering a broad range of topics related to spectroscopy and computational chemistry.
What topics will be covered in this International School?
The international school will combine a series of lectures with practical computational sessions and laboratory visits. The lectures will address a broad range of topics related to spectroscopy and computational chemistry. The practical sessions will be focused both on fundamental pen-and-paper problems and on the use of computational tools for spectroscopic simulations and for quantum chemical calculations. Significant emphasis will be placed on the use of the ORCA package for quantum chemical calculations of spectroscopic properties. Small groups of students will also be able to visit the spectroscopy laboratories of the participating Max Planck Institutes.
List of lectures:
- Introduction to Computational Chemistry (Dimitrios Pantazis)
- Introduction to ORCA (Frank Wennmohs)
- Group Theory (Serena DeBeer)
- Ligand Field Theory (Serena DeBeer)
- Optical Spectroscopy (Frank Neese)
- X-ray Spectroscopy (Serena DeBeer)
- Vibrational Spectroscopy (Maurice van Gastel)
- Spin Hamiltonians (Frank Neese)
- Magnetochemistry (Thorsten Glaser)
- EPR Spectroscopy (Alexander Schnegg)
- MCD Spectroscopy (Frank Neese)
- Mössbauer Spectroscopy (Frank Neese)
List of practicals:

- Excited-State Spectroscopy Practical (Tina Römelt & Dimitrios Manganas)
- Simulation of EPR Spectra (Alexander Schnegg & George Cutsail)
- Calculations of EPR parameters (Dimitrios Pantazis)
- Mössbauer Spectroscopy (Haowei Chen)
Facility Tours:
- Raman, UV-Vis RFQ/Stopped Flow, X-ray spectroscopy Labs, SQUID, MCD, Mössbauer, EPR Labs.
Who is this school for?
The school combines teaching at an advanced level on spectroscopic methods of relevance to molecular transition metal complexes, with instruction on how to employ ORCA as the quantum chemical software to compute relevant spectroscopic parameters from first principles. The candidates must be interested in both aspects and in their combination. This point should come across clearly from the motivation letter (see below).
Candidates who are primarily interested only in spectroscopy or only in quantum chemistry will be better served by other workshops that focus on each one of these aspects separately. Note that the school deals exclusively with molecular chemistry. Materials science and heterogeneous systems are not addressed.
What are the requirements for participation?
The students should already be familiar with the fundamentals of transition metal and coordination chemistry, spectroscopy, and quantum chemistry at an advanced undergraduate level. Familiarity with the basic working practices of computational chemistry is required.
Students have to bring their own laptops. ORCA should be preinstalled and the students must have already confirmed that ORCA is working successfully on their laptops by performing test calculations such as those described in the ORCA manual.
It is also mandatory to bring a poster on your own research work which you can present during one of our Poster Sessions. We are looking forward to seeing everyone taking this opportunity to present their research activities and to discuss those with others in a casual and nice atmosphere.
What should be included in the motivation letter?
The motivation letter should clearly state the academic level/stage of the student, the nature of their current project, and their research interests. Delineate how you expect to benefit in practice from the school and from the specific combination of spectroscopy and quantum chemistry. The background knowledge and experience in the topics listed in the requirements above should be clearly described.
This Internationale School is listed on the CCL Conference List and is also part of the DFG Research Unit FOR 5215 BioOxCat.
