# Riffle not acting as expected [closed]

I have defined two tables:

R = Table[Subscript[\[ScriptCapitalR], -i], {i, -12, -1}]
T = Table[Subscript[\[ScriptCapitalT], -i, -i - 1], {i, -12, -1}]


I want to use Riffle to interleave each respective element. When I use Riffle[{R}, {T}], it doesn't work. However, if I use the actual lists as arguments, it does. What am I doing wrong?
