Supporting information for ’ Varying Projection Quality of Good Local Electric Field Gradients of Monochlorobenzaldehydes’

Assignment, line lists and structural fits based on pure rotational experimental transitions observed for 2-chlorobenzaldehyde, 3-chlorobenzaldehyde and 4-chlorobenzaldehyde. The datasets provides high resolution microwave spectra of 2-, and 3-chlorobenzaldehyde. It also includes output files for structure optimizations, VPT2 calculations and interconversion scans for all isomers.
