How to obtain the sampling frequency of frequency data

Hi everybody, this is my first question in this forums.
I have some complex data in Matlab the absolute value of which represent a frequency response. My data extend from 1 Hz to 20 kHz and have an incremental frequency of 1 Hz.
I now need to convert this frequency responses in Impulse responses in order to measure the duration of this Impulse response. I am a bit confused though on what is the sampling frequency of my data. I need this information I guess in order to calculate time.
Is it the highest frequency of my dataset (that is 20 kHz) or double this frequency (40 kHz).
