title = "Quadrupole arrangements in solid CO",
abstract = "The group-theoretical classification of all possible quadrupole arrangements which was carried out in a previous paper for crystals such as H2 and N2 is extended here to include CO, the molecules of which lack a center of symmetry. It turns out that the quadrupole arrangement in the cubic phase is T4 with axially symmetric quadrupoles. From symmetry considerations of the quadrupoles only, it is shown that a structure similar to the tetragonal D4h14 arrangement in γ nitrogen cannot be formed in solid CO, in accord with recent experimental results.",

note = "Funding Information: Financial support was given from the Volkswagenstiftung “Forschung in Museen” to organise the first sorting workshop in Wilhelmshaven July 2016. The second workshop in Spa{\l}a (Poland) was organised with the support from the internal funds of the University of Lodz and the enthusiasm of all travelling experts. This paper would not be in this special Issue of ZooKeys without the support of the Volkswagenstiftung. Special thanks go to Antje Fischer, who always offered her technical support to solve all issues looking out for vials in the storage rooms and made specimens available to all experts involved at any time. Technical help was also provided by Karen Jeskulke solving all database issues and requests. Leon Kobe did his school practical days during the workshop in Wilhelmshaven and was a great help organizing the workshop as well as Charlotte Brenneken, who provided her student helper assistance in database entries of sorting protocols during this workshop. We thank all workshop participants who could not contribute to paper writing for their participation and sorting effort during the workshops, namely Stas Malavin, Paulina D{\c e}biec and Josh Hatton. Without the enthusiasm of Magda B{\l}a{\.z}ewicz and her team the second workshop in Spa{\l}a would not have been possible. Species level identification for Oedicerotidae and Amphilochidae was enabled by the Volkswagenstiftung allowing Anne-Nina L{\"o}rz, Bente Stransky, and Saskia Brix to invite the specialists for these groups to the DZMB Hamburg for research visits in April 2017 (Lauren Hughes and Ed Hendrycks) and June and August 2017 (Anne Helene S. Tandberg). Travel funds for Tammy Horton were provided by the EU ATLANTOS program. This project has received funding from the European Union{\textquoteright}s Horizon 2020 research and innovation programme under grant agreement no 633211. Alan Myers is thanked for his helpful and constructive review comments on our manuscript.
