E xc ited S tate P roperties of 2-Naphthol
1 Introduc tion
The distribution of electrons around a molecule determines many of its properties. In
this experiment, we will study how the proton dissociation properties of 2-naphthol
change when light is used
Experimental results can be affected by three types of experimental errors, systematic errors,
random errors, and gross errors.
Systematic errors (Determinate Errors)
Systematic errors arise due to the method itself (method err
