There are many chem programs that admit students for Spring semester. I believe financial support is only available for PhD and not Masters track at most places.
You can look at this list:

The last time I looked, the top 30 only offers Fall admission (but if you find a program that you really like, it doesn't hurt to call the admission coordinator to see what they can do for you).
Hope that helps!
