eMail non requesters on request creation

eMail non requesters on request creation

Looking for some help. I have a specific service request form for employee offboarding that I'd like to notify HR and Accounting when these requests are submitted. HR/Accounting are not technicians and the emails are group emails so they are not requesters. 

How can I have an email be triggered to two email distribution groups when a specific service request is created?
