Description
Ibuprofen
The following submission contains the data collection and processing of datasets for the sample ibuprofen under the NanEd round-robin project. Many crystals were identified, and data were collected using the continuous rotation data acquisition technique, out of which two crystals (Crystal 1 & Crystal 2), which were found to complement each other and improve the completeness of the reflection data, were selected. All the data sets were processed with PETS2 software. The table below summarizes the data collection parameters for the data sets. The following data is also included as a word file in the data folder.
