The Aroma package

NICS-scan prodedures ((a) J. Org. Chem. 2006, 71, 883-893, (b) J. Phys. Chem. A. 2019, 123, 3922-3927, (c) ChemPhysChem, 2023, 24, e202300080), the σ-only model (J. Org. Chem. 2010, 75, 2281-2288) and the NICS-XY-scan (Chem. Eur. J., 2014, 20, 5673-5688) are useful methods to determine the presence of diatropic and paratropic ring currents, especially those resulting from only the p electrons (aromaticity and antiaromaticity), local and global.
Aroma is a plugin package that has been written by Dr. Anuja Rahalkar (a former post-doctoral fellow in my group) that automates these procedures for using with the Gaussian 09, Gaussian 16, NBO 6, NBO 7, Orca 5 and Orca 6 software packages.
Using Aroma circumvents the need to manually build the appropriate input files and saves the user the difficulty of manually handling vast amounts of numerical data, making the use of the NICS-scans, the σ-only model and NICS-XY-scan easy and accessible.
Aroma 2.0 accepts standard Gaussian and Orca inputs, outputs or checkpoint files as inputs for geometry. It has also the possibility to accept a non-standard input file (see the manual).
It can automatically perform (on request) geometry optimization and a frequencies calculation.
It automatically generates input NICS-scan files for user-defined rings (and bonds and atoms in the case of NICS-XY-scan) using a user-defined BQ (or H: in Orca) range ((defaults are 0-3.9 Å, 2-5 Å) and step size (defaults is 0.1 Å), as well as σ-only input files, and subsequently runs the appropriate Gaussian and Orca jobs.
In addition to the standard Gaussian/Orca output files, Aroma generates text files that contain all the NICS-scan data, and, if NCS and/or σ-only model procedures are requested, also text files that contain the π-MOs contributions to each of the BQs’ chemical shifts and the NICS-scan results for the model. These files can be read by standard software (such as MS-Excel, OriginLab) for the analyses.
Finally, Aroma 2 produced a text file, containing the results of the analysis: For the traditional NICS-scan (reference a) a 3rd degree polynomial fit and the calculation of the NICS(1)p,ZZ value for each of the rings that are studied. For the NICS-scans at higher distances (references b and c) this file contains a two-parameters and three-parameters on-linear line fitting to providing òNICSp,ZZ and NICS(r)p,ZZ for r=1 and 1.7 Å.
Aroma is an open-source program. The (Python 3) source code can be downloaded from github. Stand-alone binary versions for Linux, windows and Mac-OS can be downloaded from this site.

We kindly ask users to fill in the forms (in the download links) before downloading. The e-mail addresses will be served only for updating about new versions and bug fixes.

The manual, including installation instructions, is available for download Aroma 2 manual.
