Question

(Identifying unknown ketone) Organic Lab. I took these spectra in lab, I know it is a ketone no other functional groups, or haildes - just need to find the chemical formula. I think it might be 2 or 3 hexanone or 3-Methylpentan-2-one / 4-Methyl-2-pentanone or 3,3-Dimethyl-2-butanone but not sure

I cannot take another IR spectrum
