Smiling with S.M.I.L.E.S :)

Assalamualaikum. 

Today, we're going to talk about SMILES.

Uh. No. Not that smile.

Cute. But still, not even that close.

What I mean by SMILES here is 

simplified molecular-input line-entry system.

Read on to know more :)

The term canonical SMILES refers to

the version of the SMILES

specification that includes rules 

for ensuring that each distinct chemical molecule

has single unique SMILES representation.

While the term Isomeric SMILES refers

to the version 

of the SMILES specification

that includes extensions

to support the specification 

of isotopes, chirality,and configuration

about double bonds.


For your information dear readers, SMILES supports all elements in the periodic table, and, an atom is 
represented using its respective atomic symbol. 


When using SMILES, single bonds are the default and therefore need 
not be entered. For example, 'CC' would mean that there is a 
non-aromatic carbon attached to another non-aromatic carbon by a
 single bond, and the computer would identify the structure as the 
chemical ethane. 

Here's a table of some SMILES bonds:

single	-
double	=
triple	#
aromatic	:

So we can conclude that SMILES is generally considered to have the 

advantage of being slightly more human-readable. :) Wow.  

And for more info, here's the link of a website that clearly explains 

what SMILES is : Smile and Click Here! :D

Here's a few examples of drawing using SMILES by CHEMSKETCH!

and...

Yes. That's all for now. 

Until we meet again~

Salam alaik :)
