Context :

Aims : We intend to establish the X-ray properties of Swift J0732.5–1331 and therefore confirm its status as an intermediate polar .

Methods : We analysed 36 240 s of X-ray data from RXTE .
Frequency analysis was used to constrain temporal variations and spectral analysis used to characterise the emission and absorption properties .

Results : The X-ray spin period is confirmed to be 512.4 ( 3 ) s with a strong first harmonic .
No modulation is detected at the candidate orbital period of 5.6 h , but a coherent modulation is present at the candidate 11.3 h period .
The spectrum is consistent with a 37 keV bremsstrahlung continuum with an iron line at 6.4 keV absorbed by an equivalent hydrogen column density of around 10 ^ { 22 } atoms cm ^ { -2 } .

Conclusions : Swift J0732–1331 is confirmed to be an intermediate polar .
