When I made my NMR spectrum, I forgot to print it in #"Hz"# as well; how do I get coupling constants in #"Hz"#?

You don't need to do much more if you already got the chemical shifts in
All you have to do to convert to
As an example, you should notice that the spacing between the shorter and taller peaks near
That likely means those protons are "communicating" and they happen to be neighboring.
These differences are approximately
If you have a
#Deltadelta ~~ "0.012 ppm"#
#=> color(blue)(J_"HH")#
#= "0.012 ppm" xx "300 MHz"#
#= 0.012# #cancel("M"^(-1))# #xx# #300 cancel("M")"Hz"#
#=# #color(blue)("3.6 Hz")#
So once you find your chemical shifts, just choose the ones you want to find the coupling constants for, convert to
