What is the chemical composition / empirical formula of Herpes Simplex 1?
The Herpes viruses have a unique four-layered structure: a core containing the large, double-stranded DNA genome is enclosed by an icosapentahedral capsid which is composed of capsomers. The capsid is surrounded by an amorphous protein coat called the tegument. It is encased in a glycoprotein-bearing lipid bilayer envelope 1.




You can watch an animation of infection and steps of replication here, and below the video, they say that 


  HSV is a nuclear replicating, icosahedral, enveloped DNA virus. The HSV envelope contains at least 8 glycoproteins. The matrix or tegument which contacts both the envelope and the capsid contains at least 15-20 proteins[2].


In this definition of the structure, they at least assigned some values to the makeup. Additionally, in wikipedia, the viral genome is listed which I would recommend you take a look at as well. It can be found here but here is the synopsis of the table 

UL1 through UL56
US1 through US12
RS1, ICP0, LRP1, LRP2
RL1, LAT
