Subnormal operator on a Hilbert space and its spectra have been studied by many authors. The aim of this work is to present some ideas on how to obtain new results related to some spectral properties of the subnormal operator. To show that we have used a particular type of operators as an example, which is represented by certain infinite matrix. We have reached new results that have been presented in the form of theorems.
